JabRef 5.1--2020-03-10--d5ee20b
Windows 10 10.0 amd64
Java 13.0.2
In the settings I deactivated the "create backup file while saving" option.
I also deleted the *.sav file from the filesystem.
But the savfile is still created when starting JabRef.
When closing JabRef it is gone.
EDIT: The behaviour is not always reproducable. But please see the attached video which contains different behaviours.

Makes no sense for me.
