V13 backup to removable media retention issues

[bishoptf]

Running v13.1 software appliance and we created all new jobs migrating away from our v12 instance. One of those jobs is a backup to removable media that is rotated weekly. Pretty much set it up as how we had it running under v12 but starting getting emails about disk space and finally ran out of space even though retention was set for storage space. Looking at the directories where the backup reside it appears that it's not pruning or deleting the old jobs properly. The backup repo is a linux box and we have the option set for rotated drives and had the option for continuing backup chain if present but have changed that to delete backups belonging to this job.

Really not sure how to address the issue, on the console it states for one of the vm's that it has 1 restore point but when I look in the directory it has files for all of august. Can someone explain how retention and rotated drives is supposed to work and how I go about cleaning up the existing jobs when veeam console does not show the other restore points?

Thanks
