Hi Di,
Other than the treeview being collapsed by default in the second picture, the images you provided unfortunately don't really show us much about the differences you are seeing. A couple questions to clarify:
- If you click the + icon and expand the 2.7.1 treeview, is it missing records?
- If you click on the "Browse as list" link in the right-hand sidebar of both versions, is the count of records shown in the browse page for that fonds different between 2.6 and 2.7.1?
One setting you might want to double-check is your Items Per Page setting for the full-width treeview. If this is a large fonds, I would recommend that you try setting this value to 10000 rather than the default 50. See:
Be sure to clear your browser cache before re-testing, or use an incognito/private browser window, where the cache is typically disabled by default.
Let us know if updating that setting helps! And if not, hopefully by answering my questions above we'll have a better sense of the issue and can provide further suggestions.
Cheers,
