Local copy does not get removed automatically

Hello,

We have the following settings:

Files backup schedule: Weekly and retain this many scheduled backups 1
Database backup schedule: Weekly and retain this many scheduled backups 1
Choose your remote storage: Dropbox
Delete local backup: ticked

So we expect that Updraft will make a backup, then upload it to Dropbox, then remove the local copy so that it does not occupy disk space on the server. However, we have to remove the copy manually.

How can we make it remove the local copy?
