I'd check the seating first because our FR10 spacer block is already tilted before lifting, but the response so far has been another pickup offset; I can't judge those changes while nobody has measured the tray contacts.
Get maintenance to inspect the tray and tool with the station isolated, then compare the physical setup with the last working one. More offsets will only bury the trail
A damaged pocket insert was holding one corner high, and maintenance has replaced it; the integrator still needs to review the offsets before we run that tray again.
