Delete DSO Change Logs in Process Chain not working in BW 7.40

Hi Everyone - We recently discovered that DSO change logs are not being deleted in the process chain we have that runs weekly.  We're not sure when this started but we upgraded to 7.4 in May.  I've looked at other discussions  on this, but nothing I have found helps us.

I've checked table RSTSODS to ensure that User Application = 'CHANGELOG'.  This is a 7.x DSO and manually deleting them from the manage screen -> Environment -> Delete Change Log Data does work, but this is not ideal. We ran program RSAR_PSA_CLEANUP_DIRECTORY and there were no issues.

Here is our deletion variant:

Here is the log from the last run:

Any help would be appreciated.

Thanks!
