I can't reproduce this with backtintime 1.2.1 (from repo-oss) and kernel
5.3.18-150300.59.101-default .
Dwain, can you try with an updated backintime 1.3.2 from Archiving:Backup?

In any case we are in the very last few months of support for openSUSE Leap
15.3, I suggest making plans to upgrade your system overall.
