Hidden key bindings

My friends and I have been experiencing an issue since launch where we rebind the helicopter and jet firing buttons to our own choices (mine happens to be the spacebar), only to find out these keys are already secretely in use as a tertiary option for other flight options (spacebar being also used for pull up on jets).

the option for a tertiary key is great, but it would be nice to see those hidden key options and have an option to unbind them all, or straight up remove them.

I'm unable to keep track of whether or not this issue has been resolved as i've done the task of unbinding everything and rebinding them in the hopes that doing that has removed any of these hidden binds.
