The retained sleeve sits level in its pickup pocket, then rises at one edge as the fingers close. Several pickup edits are in the current FR5 job. I have requested a comparison of the fitted contact faces, mounting stack and intended assembly before anyone adds another correction.
Include the actual first-contact view in that request. We had three people discussing where the arm ended up while the useful clue was where the part first moved. Has maintenance got the identified sleeve as well as the video?
