Cannot Add group membirship to clients with Closed loans with period fees

Clients that have closed loans with periodic monthly fees, cannot be added to groups
repro:
1-Search for a client that have a closed loan (loan must have a periodic monthly fee)
2-click on Edit meeting schedule / Add Group
3-Add Group membership
4-search for a group
5-error received is :"Membership to group with different meeting frequency cannot be changed, as active periodic fees exist." (screenshot 2)

Bug Found in table
account_fees
all closed_fees should have the fee_status id changed to 2.
i found that all old loans have this field as null.
As a workaround, update all fee_status fields for closed fees to 2 instead of null
