Since the Research website is inside the default uthscsa.edu website, research site editor permissions are determined by the menu system.
The research editor will only be able to edit pages that have a menu entry under New Research Menu.
Note: breadcrumbs are handled separately. Edit the page to check to see if it is in the menu system.

The above screenshot says Not in menu under Menu Settings so the Research site editor will not be able to edit this page.
Expand the Menu settings by clicking on it. Check Provide a menu link.

Under Parent link, scroll thru to find the appropriate location in the menu system under New Research site LIVE.
If the page is not in the menu system somewhere under New Research site LIVE, then the research site editor will not be able to edit the page. Be sure it is a child page under New Research site LIVE.
Save the page.
