Can't Click Accept And Messes up my leaver buster

I have a leaver buster and whenever it finishes the the AFK check pops up I click it, then when someone else doesn't accept I can't click accept on the second on that pops it. This bug wastes 20 minutes of my time and makes me reset my leaver buster not making counting it as me waiting for one. Hopefully someone can help me fix it or respond.
