AOE Next Click messed up repeater

What I mean is when I was making a keymap for my AOE, and Summon Infernal for my warlock (which uses target on the ground to summon him, don't ask me why seems kind of odd it would use that but all well) and what I did was set the F1 key to cast it, and when I clicked it, I was thrilled it worked like I wanted it to. However when I next tried to use the repeater to respawn after a wipe, I noticed that it only was repeating on my warlock's window. I switched to a different toon, and repeater worked fine. I reset the UI and it still persisted, I later logged off, and relogged back on, and noticed repeater working again.

Guess its more a hiccup somewhere, but not sure how to make it not do that, other than make the action cause all windows to click if it happens again, that way it'll keep the repeater on all windows.
