Honestly it’s either a glitch or you are overlooking some hidden button. I would try 2 things, first unhide all your buttons and see what is actually in the widget, if that doesn’t reveal any issues then try restarting the editor. I know it sounds silly but unreal does this occasionally just has weird random bugs that go away on restart. Another thing that comes to mind without actually seeing more of your blueprints is if you duplicated the widget to make a new variation since one wasn’t working initially and kept both old and new, if you didn’t change the widget class where you create it to the new version you would still be creating the old version with the bad button not the new one. Just another thought if it applies.
