Right and left mouse buttons are not working

All my other input keys are working just fine. I’m working on an RTS style game and I’m using the new UMG+HUD interface to lock my mouse on the screen. Whenever I try to create events using left and right mouse buttons nothing happens while any other key would work.

Another problem: After setting up my landscape and adding some actors to it. The single line trace by channel seems to ignore all my actors and only hits the landscape. Please help!

It was in the setting section just disable touch events and it’ll work
