To replicate: Checkin some items, note they show in the 'Checked-in items' table Checkin an item with a hold/trnasfer and confirm Note the table is cleared
Can't reproduce the bug on my Koha
Ah, yes, confirming a hold doesn't trigger it seems But cancelling a transfer still triggers this issue.
Cancelling a hold via the hold modal on check in triggers this issue as well.
Cannot recreate on master
