First after the update all the schedulles doesn't worked, they appeared to be ok, but the backup did not started.
Then I edited and saved the schedule trying to fix the problem, but when I save, the schedule disapears from the backup that I edit and suddenly appears on another backup (

So I had to delete all the schedules and create again, this works, but if I try to edit the schedule the problem happens again. So every time I had to edit a schedule I need to delete and do it again.
This started to happen when I updated to version 7.
