Timebased Backlog policy doesn't work as expected and data is not deleted.

Timebased Backlog policy doesn't work as expected and data is not deleted.
How can I know the mapping between ledgerId and entryFile? So that I can do further trace.

Enviroment: Pulsar 2.9.3 cluster and applied the fix of https://github.com/apache/pulsar/pull/18037/files. JDK 1.8

BACKLOG config：

[root@cg3 apache-pulsar-2.9.3]# bin/pulsar-admin topics get-backlog-quotas persistent://goldwind/iothub/prop_data-BZ-GRID-realdev-Guarantee-308043656855769088 -ap
"destination_storage BacklogQuotaImpl(limit=106300440576, limitSize=106300440576, limitTime=43200, policy=consumer_backlog_eviction)"
"message_age BacklogQuotaImpl(limit=107374182400, limitSize=107374182400, limitTime=43200, policy=consumer_backlog_eviction)"

RETENTION config
[root@cg3 apache-pulsar-2.9.3]# bin/pulsar-admin topics get-retention persistent://goldwind/iothub/prop_data-BZ-GRID-realdev-Guarantee-308043656855769088 -ap
{
"retentionTimeInMinutes" : 1440,

Seems the markDeletePosition of zombie subscription is not moved by backlogManager.
