Keybinds sometimes reverting?

I change my crouch/prone and sprint keybind to my front mouse button, and back mouse button respectively. I did that in BF6, and unbinded it from the gadgets they were originally assigned to and 80% of the time it works normally, however it happens often enough to where i will try to crouch or prone, and it pulls out my gadget AND goes crouch or prone. Its as if sometimes the keybind recognizes the old bind that is no longer assigned. It can be pretty annoying, trying to crouch behind cover and i end up pulling a land mine out for no reason. Anyone else experience some keybind issue like that?
