Number of backups

I’m running a server using HestiaCP with panel v1.10.5 in a Debian 12 machine.
I’m only using the default package, which has been configured to 1 backup, but the system is still keeping two backups instead (current day and the day before).
I want to avoid running out of disk, since the backup of a couple of host require a lot of disk space.

I’m not worried about the number of backups, since they are transfered daily to a remote backup server that has plenty space and keeps a copy of the last 30 days.

Why is it still keeping two backups?
Have I missunderstood any concept or is it that I should configure something manually?

By the way, thank you very much for the awesome people running HestiaCP, specially in moments like this.
