Versioning: macro %week% gets resolved in the settings

[Frank_G]

Hi
I'm trying to understand the versioning functionality.
If I setup a backup and use the "move old files to specific folder" with a sftp-Server, than I put in a line like

sftp://..../revisions/Daten/%week%

If I run the backup and recheck the settings afterwards, the macro %week% has been resolved and replaced in the settings, i.e. the backup of the next week would again run into the folder Daten/25 instead of the correct folder Daten/26 .
Please see image.

Of course, the variable must be resolved within an actual backup, but it should not be copied back to the settings line.
Does someone know how to prevent the programm from doing so ?
Thanks
Frank
