[Snapshot Pro] Backups are running rampant

I have my sites to usually have a backup and then delete everything older so that there is only one file, since I’m low on space and in several cases I have had several files on my server and in the hub of backups. Why is this happening if I have it configured to only have one file before deleting older ones?

This morning I deleted a bunch of files and I left bwgarden alone so you could see what’s showing in the hub. Also on my server there are three huge backups that are eating valuable space.

Thanks for the help.
