Windows 10 Mobile didn't save my messages?

[Windows Central Question]

Hi all!
I updated my Lumia 930 to Windows 10 Mobile Preview, but I had to roll back to WP 8.1 and hard reset because of a phone reparation.
But when I got back my phone and restored everything, the messages which were sent and received while I used the W10M disappeared. But I'm sure that the message backup was turned on.
What should be the problem?
If I update to W10M Preview again, will they be restored to my phone?

They are there but from experience it seems they only restore when you go back to w10m
