The keyboard button 'Delete' (or 'Del') cannot be set as a shortcut in keybindings.

System

I don't know if anyone posted this already, but I didn't find any post on it. The default keyboard shortcut for 'distribute shields' used to be 'Del' (on Holodeck it still is) but on Tribble it doesn't work. Also, I tried to set it manually - no luck. Pressing the 'Del' button just clears the shortcut, and it does not appear in the special keys combo-box. I tried to report this bug in-game a few times but it just gives timeout.
