Hi, Mango Team
The bread crumbs path shown for the 'File stores' UI does not allow navigation into higher up level when a file is being edited. In order to navigate to a different place in the 'File stores' structure after editing a file, one has to navigate away from it to a different place then navigate into the 'File stores' again.
Below is a screenshot illustrating what I meant:
