B-J-J would be "Bat, Jersey, Jersey" and should be listed exactly the way shown in quotes inthe Note2 field. Note should have "MEM, SN##" (whatever the SN number actually is, if anything). And yes, the Name field should only have the player's name.
Sorry, that's one of those sets I looked at 1,000 times and kept skipping it.
What might be helpful is editing the set in "form" mode, and only listing Name and Note 2 - that way you can see what should go in Note2, and put it in. Note (depending on SNs) may simply be editing that en masse.
