I need to double click to register a click

Hi there

I am using UE 5.5 for a project. I tried upgrading the 5.6 but the 3D text no longer works so I decided I need to stick to 5.5 and thus can’t upgrade to test if this bug happens in 5.6 also.

In my game I turn clicks into projectiles going from the 2D clicked position into the world. This has worked perfectly ever since I got started with the project back in 5.2 but this week I changed my game-over logic so instead of just loading a widget on top of the scene I now load the game-over logic in a scene of it’s own.
Now when I go back to the level i need to double click to spawn a projectile

After a bit of searching i noticed that in making this change to my game-over logic I also told the game over scene to set game input mode to UI only and when I load the level I set it to Game Only and THIS apparently breaks something.

Simply by changing that single blueprint node to set the input mode to game-and-UI my clicks once again function as clicks like normal.
