Odd right stick behavior after water damage repair

My daughter dropped my pro controller in the bathtub as I was filling it. I disassembled it, dried it, left it in rice overnight, and reassembled. I dry fit and tested it and it luckily worked fine with a left stick calibration. Once I fully reassembled through I had a right stick problem. It seems like it just needs calibration (just a bit off and pushes down) but when I go to calibrate I can’t. The “pre-screen” that shows stick movement does register all 4 directions even though they are off a bit and push down, but when I push X to calibrate and get to that screen, it doesn’t register that I’m pushing the stick left as instructed and I can’t get further.

I’ve reopened it, removed the control stick knobs, cleaned with alcohol and compressed air and reassembled. I’ve also tried disassociated the controller with the switch and re-pairing. But I get the same result.

Clearly it sees the stick moving in the various directions so I’m at a loss as to why I can’t attempt the recalibration and my efforts aren’t getting me anywhere.

Anyone have some advice for me? This is the limited edition TotK one and I really want to preserve it!
