Not sure if anyone else uses the "Collapse Folders" function available in the Treasure Box, but it has been acting a little wonky for me as of late. The correct behavior is that it collapses all your Marketing Activities folders when you flip around within Marketo, or close the tab/window and open it up again.
As of late, though, it closes most of my folders, but always leaves the same ones open (and there's seemingly no reason why those ones are open and not others).
Figured I'd see if anyone else has experienced a similar issue?
