Entity is unknown error in log

When starting zigbee2mqtt I get two errors in the log:
error 2020-05-28 19:19:03: Entity ‘tint02’ is unknown
error 2020-05-28 19:19:03: Entity ‘tint’ is unknown
I think these are leftovers from early experiments, the nodes are no longer in the network and force remove does not clear this error. All seems to work so no big deal but is there any way to clean up the database to get rid of these errors?
