In particular the YFNX (and possibly the YFNS too) don't seem to pass it along properly, therefore they need to be in a lower page than the OSX3. Make sure you have them plugged with this condition and check if the issue is gone.

Thanks Ángel!
That did the trick. I suspected it was something along those lines. I probably should have tried this before posting here.
