I have the exact same issue. I wrote a thread asking for help on reddit earlier, and I really wished I knew about this beforehand because I pretty much bought this controller for FFXIV like other people in this thread.

I understand the issue is not major since only a "handful" of people might be trying to use this controller and that it's relatively new (still about a month, though...), but it would be great if you could report the issue to the devs in that it's most certainly a client-based issue as the controller works fine on everything else.
