'Replication health' continues to be in the '(Re)initializing automatic data distribution' phase

FDB version 7.2.0
Cluster size: 18 nodes in total, Redundancy mode use three_datacenter, 6 nodes per DC

Here is what I see in fdbcli:
```
# fdbcli
Using cluster file `/etc/foundationdb/fdb.cluster'.

The database is available, but has issues (type 'status' for more information).

Welcome to the fdbcli. For help, type `help'.

What could be the reason?

Start with the fdbcli status output and the data_distributor trace, then inspect DDTeamCollection.actor.cpp at isValidLocality and the BuildTeamsActor call sites named in the stack trace. Reproduce or trace the automatic data-distribution initialization behavior and determine whether the reported failure explains the persistent status; done means identifying a supported cause and a concrete corrective direction.
