Google Console and AMP

Hi, good morning,
I have a problem with AMP in Google Console that will not be fixed.
The problem is coverage, it says that the referring AMP URL is not from an AMP page and that the AMP version is indexed
How could I fix it?
these are the pages that are giving me problems:
https://www.prosutelsistemas.net/amp/
https://www.prosutelsistemas.net/pruebas-de-nivel-a-b-o-c/amp/
https://www.prosutelsistemas.net/instalacion-y-puesta-en-servicio/amp/
https://www.prosutelsistemas.net/aviso-legal/amp/

Best regards
