Button style trouble

I have a trouble.
I added button in to Hud blueprint. Set size and image(normal, pressed). If I click on button for movement, all of my changes are reset. UE 4.10 project for mobile. What should I do?
Sorry for me english.

Welcome to the forum (:

First of all, you need to post screenshots of all blueprints that are involved. We can’t help you without seeing your Code/Blueprints,
because we can’t see what you are maybe doing wrong!
