PS2 SF:AE always holding u/f

Installed a Ascii optical into my stick recently and it works well with every game. Played a little AE last night, and the stick seemed to be in permanent u/f. Wiring looks fine, tested again with ps2 CvS2 and DC MvC2 / converter. Series A pcb I think. Anyone know what’s going on?

Sorry, I don’t have an exact answer but:

Weird. I doubt just fiddling with the wires a little will work for everyone though. Maybe HSF2 enables analog by default and can’t be disabled, so that dpad and analog stick are both functional at once. I didn’t see a place in the option menu to disable it, unlike in 3S.

Maybe your analog sticks aren’t centered? Can’t think of anything else besides that.
