Provider used "move subscriptions" functionality introduced in PBA-E 6.0 to move domain subscription from account A to account B Subscription is moved and is shown in list of subscriptions under account B in POA and PBA.
In POA domain is shown under correct account (account B). However in PBA domain is still shown under old account (account A) on "Registered Domains" screen.
The cause of the issue is a bug #PBA-62248 ("Transfer subscription between 2 accounts is not changing the owner in PBA side").
Please contact Odin Technical Support to fix this problem for affected domain(s).
