Please provide any additional information below.

 Since my previous error ticket was deleted with no explanation I am going to start a new one.

It appears that the drop down menu on the right is broken,all additional mods won't show up any selections in that second drop down menu.

  If you feel that I shouldn't post this here, please tell me.
