Rudder

The config file contains this:

#
# Schedule option for automatic cleaning
# Automatic cleaning can be scheduled:
#  - every hour at the minute past the hour of your choice
#  - every day at the time of your choice
#  - every week on the day at the time of your choice
#                                                                                                                                                                       
# Default frequency: daily
rudder.batch.reportscleaner.frequency=daily

We must add the available options (I assume "weekly" and "hourly"?).

IIRC, this was introduced in 2.6.*, so needs to be fixed there. Please check, and apply the fix to whichever version is appropriate.
