The other day I noticed my main custom template had suddenly been deleted.

So I decided to make a new one with the same changes as the deleted one. However, now the templates I create keep disappearing and reappearing. I've tried different browsers and computers.

I haven't edited any templates for a while before this incident - so I might just be making some basic mistake.

Please watch this video to understand the problem:

I found a workaround. I think the problem had something to do with odd and even pages.

Creating 2 identical templates with the same name somehow fixed the problem.
