Thank you so much for this answer, sorry it took me so long to reply.
It looks like the site uses flexible content on one of the pages and I don’t have the time to change that, so I will have to leave it as it is.
The site does not have any subscribers and is a very simple static design so, from what you say, it looks like I will be okay to ignore the warning until I have the time to do something with it?
Thank you again for taking the time to respond.
