Hi.
Check input settings it could be that invert is checked (you could also hold space bar to see if it goes to 'false')
Try setting a different button name.
so I've already tried assigning a different input(no change).
I checked and made sure that invert was not checked.
after confirming it wasn't checked, I tried inverting it just for the heck of it(no change)
I even tried removing the button from the input in the input manager(no change)
I'm going to create a new sfm and see if it keeps happening
