Running out of ideas after after 4 months of Mobility Warnings

Does anything have a moment to take look at a page for me? After ignoring Google Consoles Mobility Issues - Clickable Elements too close or Content wider than screen for the last 4 months  - I noticed that some of the pages these refer to have not only started to lose ranking, but one in particular has disappeared from search. 

I know general advice is to ignore some of Google Consoles mobile warnings - but these are not going away and consistently warn me that the page is not mobile friendly each month  (though, as we all know, when entered into Google Mobile Friendly Test these pages have no issues) and I certainly cannot see where the issues lie, even after getting friends to view the pages on their devices.

But now page ranking has come into the arena, I am beginning to worry.  I have installed Chrome Lighthouse ( most confusing) without seeing an error related to these issues. (though finding lots of others that appear to be in the realm of Sq Sp code than anything I can do) 

I wondered if anyone might take a look for me and see if they can spot either of the Clickable Elements too close or Content wider than screen” mobility issues.

Although the mobility warnings affect a half-dozen pages on the site, it is specifically this one that I am most concerned with.
