[Zubersoft]

If you use a file browser to navigate to /storage/emulated/0/Android/data/com.zubersoft.mobilesheetspro/files, that is where the mobilesheets.db backup files are stored if you have set the storage location to an SD card folder. If you don't see older backups in that folder, then I can't really explain that as resetting the settings should have had no impact on the backup files.
