Single post templates: What happened and how can I recover/delete them?

Hello, TagDiv team!

Yesterday, I wanted to use one of the test post templates I had made a few months ago, from Post Settings/Post Templates.

But when I wanted to use them, they didn’t display in the post. But the ones we actively used were displayed.

So I went to Newspaper’s Theme Panel, and there I found the same templates. I assigned one to a category, to test, and nothing happened.

Then, I went to Cloud Templates, and only the ones we actively use are displayed, but the others are gone. And I never deleted them.

So…

1. Is it likely to recover those test templates (ideally)?

2. If not possible, how can I delete them from Post Settings and Theme Panel, to try again from scratch?

Thank you very much!

Hello, Bettina!

Some do, but others were created from zeros. And the ones I took from Cloud Templates already had high customization.

If there is no way to recover them, how do I remove them from Post Settings and Theme Panel?

Thanks!
