Kerbal Space Program

The mobile processing lab's clean experiments action can't be added to any action groups. I've encountered this issue regardless of being in the VHB/SPH or piloting the vehicle, even if there's a scientist onboard inside the lab, with or without a restorable science experiment available, and whether trying to bind the action as a toggle/axis/kal controller action. I can only assume this bug happens because the clean experiments action is only intermittently activatable depending on if you have cleanable experiments on your vehicle but I really have no idea. I also made sure to uninstall any mods I had which didn't make a difference either.
