Unassigned keyboard Key causing issue

Good day,

I assigned few keys to control my character in the game. Since the update 5.1.1 from 5.1, my “space” key does not longer work on any of my controls even if it is assigned correctly. If I replace the “Space” key, the action is now working. I have the same issue with the “G” keyboard key. (Yes the physical keyboard keys are all working)

The “G” key is not assigned anywhere in my project and still the “G” key is being use to complete the previous assigned actions. If I assign any other key to the action that the “G” key activate, the action works fine with the new assigned key but the “G” key still activate this action even if it is not assigned.

I only use one ActionMappingContext.

Any Idea?
