Automated backups not available for restoring

We just activated automated backups on our Moodle, and they are running fine via cron; however, when we go to a course's restore page, the automated backup section is clear even though the backup of the course was made successfully.

Furthermore, the result of the following query is empty: select * from mdl_files where filearea = 'automated';


This is our setup:




One can see that the .mbz was generated for the course:


And there are a bunch more that were generated on the same day:


The backup report shows that the course backup was completed successfully:


Nevertheless,  the automated backup does not appear in the restore area of the course:


I even tried switching to another role that has the moodle/restore:viewautomatedfilearea capability, but still no luck.

Is there any reason for this system behavior? Are we doing something wrong?

We are running Moodle 3.11.6 on EKS.
