Why won't my Player Controller execute anything tied to an "On Pressed" event

I followed some instuctions found below in a thread talking about my issue but none of the posted answers are working for me.

I made sure my “Block Input” checkbox found in “Default → Input” for my player controller was set to false, also I tried setting “Enable Input” like in the first response and I also created a new action mapping for it in my Input Settings…

Yet when I press Alt, or command or whatever none of those executions will fire???

Any help would be super appreciated! Again I’m trying to call the event from my player controller when I hit ALT or something else.

Wow ok UE4, I guess all I had to do was close and reopen my project and it works now…Glad I spent an hour making this post and troubleshooting only to found out UE4 is wigging out as usual.

Also, I don’t know why but when I hit “Play” it wont recognize my buttons being pressed unless I click somewhere within my viewport first…wut? You would think that it would stop recognizing buttons being pressed in the editor and start recognizing them in game after you hit play but whatever. Maybe this has been fixed in newer versions, I am working on 4.15 so it could be my fault.
