Blank menu when opening properties on a GnuPG Key

When right clicking on a PGP key and clicking properties, it works fine the first time, and opens the properties menu correctly. When closing that properties menu, and then clicking properties again, it does not properly open the menu, only showing a white properties screen. Waiting does not seem to help. In order to see the properties for a key again, you must reboot the computer, (at least that is the only way I have found). Have just been using terminal instead for this, which works fine.

EDIT: Opening the properties of another/different key (Key B) (not the bugged one), will work for the first time. Once the properties menu is closed, Key B properties menu will also become bugged, and have the same white screen problem when trying to reopen the properties menu of Key B.

Hope I am explaining this well, and can answer any questions.

Thanks for the help!
