Good Morning.
I am unaware of the existence of those caches of my theme that you mention to me. Where are they found?

On the other hand, to tell you that in new pages that do not have a cache, it does not work for me either.

I attach a small video of the process that I follow, in case I am doing something wrong.

Thanks and regards.
