Different colors on Preview and runtime.

The tab type is not working properly. The white dots are showing differently after compiling.

Preview:

After compiling the app:

I also noticed the following behaviors with API 24 and 26:

• Progress type not showing properly:
  

• Fleet type is simply invisible unless I run it on a higher API.

This is the XML:

<FrameLayout 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"
    android:layout_width="match_parent"
    android:layout_height="match_parent">



    <com.aceinteract.android.stepper.StepperNavigationView
        android:id="@+id/stepper"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/toolbar"

        android:visibility="visible"
        app:layout_constraintEnd_toEndOf="@+id/toolbar"
        app:layout_constraintStart_toStartOf="@+id/toolbar"
        app:layout_constraintTop_toBottomOf="@+id/toolbar"
        app:stepperItems="@menu/stepper_menu"
        app:stepperTextColor="@color/white"
        app:stepperType="progress"
        app:stepperWidgetColor="@color/purple_300" />

It's the same as above. Everything seem fine in the preview, but once I compile the app, these glitches start to show.
