Custom string attribute breaks Android Studio's ConstraintLayout preview

I created a custom view extending the AutoCompleteTextView. Also I have custom attributes related to that. When I set the custom string attribute value in the layout, the constraint layout design screen preview stops properly working. When I remove the custom string attribute, the constraint layout works properly. This only takes place at design time, there is no problem at run time. I reinstalled and updated Android Studio but it didn't help me. My codes and screenshots are below:

broken view when setting custom attribute named model_field

attrs.xml:

        <attr name="model_field" format="string"/>

        <attr name="search_type" format="enum">

            <enum name="never" value="0"/>

            <enum name="always" value="1"/>

            <enum name="depended" value="2"/>

        </attr>

    </declare-styleable>
