The other day as usual, I used the social pane to find a group. This is something I often do. A group formed (Proof is in the Poison) and I went to turn it off.
Throughout the quest I continued to receive requests. Yes, the party did have a horrible time and yes there were replacements.

However, I didn't mean to be rude in declining so many quests. So, in asking for advice, I was told instructions on how to turn it off. I KNOW how to turn it off. But it wasn't working. I'd click "advertise..." and it would click/unclick/click and give me an LFG icon!

Is this a known issue? If so, how is it solved? I'd really hate to ruin my future grouping endeavors.
