I tried to recreate this bug but the replace worked as it should for me. I replace a Swipe-Throw behavior with a Drag-Move behavior.Try to delete the interaction you don't need and let us know if it's still reappear after that. 

That is a nice idea. Thank you for the feedback

That is a great idea.Thank you for the feedback.

We found some bugs for Drag-Erase which will be fixed as soon as possible.

When you click the Location (X,Y) to click the whole tap, you can't click only on X or only on Y.

We were able to recreate this bug and we will fix it .Thank you for the feedback.
