Round-robin key keep repeating on alt characters

Hello, I'm actually playing Diablo 3 for the Season 4 and I've put a Round-robin key, but my problem is that when I press the key one time, my 2 other alts keep spamming it and spell keep being use everytime cooldown is available (actually it's not a huge problem because I put Crusader's Law on that key... but I might change it later).

Here's my setting : http://pastebin.com/vM9LRv0w

If anyone knows how to fix it, it was working perfectly during the last few months before I stop play waiting this season.

Regards.

Sorry if my topic is in the wrong place, hesitated between Diablo3 forum or this one.

I cant see why your 3 key round robin would behave as you have described, unless you have Disabled Key Maps.
If you disable key maps, then broadcasting will take over, at which point 3 will be broadcast to all game clients. If Key Maps are enabled, then the 3 key will be picked up as a hotkey (key map hotkeys override broadcasting), and this will then be used as a Round Robin sending 3 to each client, one at a time, as you press the hotkey.
