Transfer Error Pack 0555

Trying to transfer a Scout in My.scouting into Pack 0555 from another District same council.

I am not doing this in Scoutbook only in my.scouting as it should roll down to scoutbook.

Transfer/Multiple transaction failed. Registration record 166007765 for memberId 141026625 not found

is the error message I am getting any thoughts?

@RoderickMorgan that scout is not registered - they are in a grace period - registration ended 8/31 - they just need to register in the new unit
