ConstraintLayout unnecessary error

I'm using ConstraintLayout wrapped with layout tags for dataBinding, all layouts works fine in execution and runtime, but I got an annoying issue:

ConstraintLayout

layout

dataBinding

As you see, constraint id's say "Cannot resolve symbol '@+id/tvAccount'", seemed as errors when trying to commit, but there's nothing wrong with workflow or the app, and all works fine as intended. It's same in all xml files. Cleaning, invalidating cache etc. is not fixing it. Has anyone met the same issue ?

Edit:
XML code for splash, it'll say "Cannot resolve symbol '@+id/imageViewSplash'" when you hover on the app:layout_constraintTop_toBottomOf="@+id/imageViewSplash" :

app:layout_constraintTop_toBottomOf="@+id/imageViewSplash"

<?xml version="1.0" encoding="utf-8"?>
<layout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">

<!--suppress AndroidUnknownAttribute -->
<data class="SplashBinding"/>

<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.splash.SplashFragment">

<ImageView
android:id="@+id/imageViewSplash"
android:layout_width="wrap_content"
android:layout_height="39dp"
android:layout_marginBottom="8dp"
android:contentDescription="@string/content_description_splash_icon"
android:src="@mipmap/splash_icon"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"/>

<ImageView
android:id="@+id/imageViewSplashLoader"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginEnd="8dp"
android:layout_marginTop="16dp"
android:contentDescription="@string/content_description_splash_loading"
android:src="@mipmap/splash_loader"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/imageViewSplash"/>
</android.support.constraint.ConstraintLayout>
</layout>


Edit 2:
It's same error when you hover on app:layout_constraintTop_toBottomOf="@+id/imageViewSplash", even without <layout> tags:

app:layout_constraintTop_toBottomOf="@+id/imageViewSplash"

<layout>

<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"/>

<ImageView

After keeping layout in the editor i might have got the solution for you. The possible cause here is might be with the xmlns:bind and xmlns:android

xmlns:bind

xmlns:android

Please try following it's not showing me any error.

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:bind="http://schemas.android.com/apk/res/android">

<data></data>

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView
android:id="@+id/tvAccount"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="32dp"
android:layout_marginTop="13dp"
android:layout_marginEnd="32dp"
android:text="Account"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />

<TextView
android:id="@+id/tvPhoneValidationTitle"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Phone Validation"
app:layout_constraintEnd_toEndOf="@id/tvAccount"
app:layout_constraintStart_toStartOf="@id/tvAccount"
app:layout_constraintTop_toBottomOf="@id/tvAccount" />
</androidx.constraintlayout.widget.ConstraintLayout>
</layout>
