[Recreator Required] Default asking backup vs backup from settings

There is backup issue.
Chrome browser opens up > open Kantu, and it is asking for do yo want to do the backup?. As soon as clicks on yes it is starting downloading back up and is in size is 200 KB. But

if we do the same thing from settings > Run backup now then it is starting downloading and is in size is 2656 KB.
it had happened at my end earlier , so i thought may it is only at my end. Today i see the same thing again.
pl. see.
Thanks

Did you look inside the ZIP files? => What files are different?

Very strange… I just tested with V3.5.17 and both backups are 100% identical. => So can you please re-test with the latest version, and let me know if you still see this problem?
