In Virtualmin Backup, excluded directory dont work anymore

After the update to Virtualmin GPL 7.0-4 my scheduled backups with excluded directory set, dont exclude the directory content selected, but full backup entirely website.

Let me explain:
In scheduled backup i configure this exclusion “public_html/sitebar” so the directory sitebar will not be saved (and they work fine until Virtualmin 6.*). Now the directory is included in backup.
If I try to change the exclusion in “public_html/sitebar/*.*”, the structure of the directory sitebar is saved, but without the file inside.
So, I think there is a bug about only directory exclusion.
