Hi @HughesSD,
Thank you for your post and welcome to our community forums. We're here to help.
I'm very sorry to hear you're facing some problems with your recordings being deleted. It's possible that you have Auto-Delete enabled, which I'd advise checking if you haven't done so already.
If you don't have this set up and it doesn't explain the deletions you're referring to, please let us know. At that stage it's possible that the box itself is potentially faulty and we can investigate further from there.
Thanks,
