Table Synchronization status unknown

[RakeshThirunahari]

For some of the replicated tables, I get a status "unknown" on the subscriber when I call select * from pglogical.show_subscription_table(subscription_name name, relation regclass);.
In fact, I've discovered that 5 tables are missing when I issue select * from pglogical.local_sync_status; on the subscriber.
On the provider: select * from pglogical.replication_set_table; returns 40 lines for the set_id used.
On the subscriber: select * from pglogical.tables; returns the same 40 tables. But, select * from pglogical.local_sync_status; returns only 35 tables even if the data seem synchronized for the missing tables.

To reproduce the issue create the subscription with synchronize_data := false
