Android Studio not rendering AppCompatButton in preview and design

Question

I have this AppCompatButton :

<android.support.v7.widget.AppCompatButton
                    android:id="@+id/btn1"
                    android:layout_width="0dp"
                    style="@style/buttons_style"
                    android:text="@string/text1" />

But Android Studio designer preview displays it like this, how can make it update the preview show complete preview? :

There are errors in designer, saying AppCompatButton is raising exceptions while rendering :
