Inconsistency in scope and mobile usability.

[BingBang]

Hello friends. I have 154 pages, and the site map is up to date. When I checked in Search Console, the coverage section shows all of them completely. In the mobile usability section, the valid page count is 124 and the error count is 0. Why is there this inconsistency? There should also be 154 pages in the mobile usability section, but it only shows 124 pages.
