No-index + meta description malfunction?

Hi there.

For almost a year now we’ve have been using Rank Math’s option to avoid indexing legal pages ticking the no-index option at these three pages:
https://zeromoment.marketing/privacidad/
https://zeromoment.marketing/privacidad/aviso-legal/
https://zeromoment.marketing/privacidad/cookies/

Now all 3 appear as indexed and the no-index tag doesn’t seem to be printing in the source code any more even if the option is selected in all of them.

Also, don’t know if it’s related, some meta descriptions that display correctly at the back-end such as the one at the home page, has disappeared from the Google SERP and it can’t be found at the source code either.

Any tips?
Thank you!
