Qanba Obsidian Arcade Stick Not Working With Cave Shmups?

[Eat Electric Death!]

Anyone know why this might be happening? It was working just fine only a few days ago, I was playing Mushihimesama, Deathsmiles, and Dodonpachi with my Qanba Obsidian arcade stick and having a great time. Yesterday for whatever reason every Cave shmup on Steam simultaneously decided to stop responding to the inputs from my joystick. All my other non-cave Shmups, like Crimzon Clover and Dariusburst Chronicle Saviours, have no problem recognizing and responding to the inputs from my Qanba Obsidian so it's beyond me why the Cave games would be any different, especially when they were working JUST A FEW DAYS AGO without any changes having been made since then, at least to my knowledge.

All my Games (inclusive Cave Shmups) works with my Qanba Obsidian Arcade Stick. Set the Mode on Stick to PC and don´t use Steam Config Controller. It works like a XBOX 360/One Controller. Just played Mushihimesama - no Problems with the Stick.
