My blog has 5 tabs/categories. When the first tab is selected the appearance is fine but when you select other tabs the titles and descriptions are not appearing correctly. They are either missing or in the wrong place. The page I need help with: https://www.mats.org/category/in-the-community/
On first blush, it looks like the divs for the other tabs/categories aren’t nested the same way as your most recent (blog) page is.
In particular I see a div class=”ssba-classic-2 ssba ssbp-wrap left ssbp–theme-1″ that appears underneath one of the div class=”blog-desc” which may be throwing things off.
Which theme are you using and is it defining a slightly different template for your blog page than it does for the category pages? (See also: https://codex.wordpress.org/Category_Templates)
