[CLIENT] 'Show completed missions' has wrong click target

http://i.imgur.com/aXveS9J.png In the image, highlighted in red, is the usual click target for checkboxes (eg. Group Mobile). When click in the red area and the checkbox toggles and closes the "popup" (in case of Group Mobile) like expected.

In case of 'Show completed Missions', clicking in the red area closes the "popup" but doesn't toggle the option, which is unintended behaviour¸because it should toggle the option. Clicking in green area toggles the option and closes the "popup" nomally.
