Am I missing something? (Screen prints below)
Do you mean that you added the 2016-17 folder to favorites, but some subfolders of it are missing when Listary expands it automatically?
Exactly, 2016-17 is added to favorites and V4 expands the folders correctly automatically. By contrast V5 only lists some folders at the second level of automatic expansion.
Here, in case it helps, is how the menu is set up (screenshot from V4).
