Oddity in Search Console

[Contractor]

In my Search Console I have 44 pages submitted in my sitemap and the coverage shows that all 44 pages are valid and indexed. No issues with them.

But oddly enough it only lists 27 pages in Mobile Usability. What about the other 17 pages? They are not listed as errors, just are just not showing at all.

Any ideas?

Coverage:

Mobile Usability:

Now its down to 26 Valid pages and 0 Errors.

Does anyone know what this could be? is there a way to force SC to check mobile usability of pages? Shouldn't it draw from the sitemap (which works perfectly in the Coverage section of SC).
