Default keyboard/mouse inputs

Hey guys having an issue with all of my new projects as of late where the default keybindings no longer seem to work and I have to manually go into my pawn blueprints and change the keys. When I try to import my older defaultinput.ini it does nothing…I am sure the solution is simple and staring me in the face. Any help would be appreciated

Are these actual new projects or ones you have transferred to a new version of the engine? Plus what engine version are you using?
