Timestamp Error on the `fdbbackup status`

There is something wrong with my backup timestamp, today is May 11,and the backup timestamp is still March 16. The time of all the CVMs is correct, and the fdbcli --exec status shows the correct timestamp。How to modify the timestamp of fdbbackup?

I compare the timestamp_version of cluster(fdbcli --exec getversion) with the backup timestamp_version(fdbbackup status), the results show that the fdbbackup version is updated correctly with the database, but fdbbackup timestamp is wrong.
FDB – 6.3.23
