Expanded option has no effect

Not sure if it is related, but checking the "Expand all menu links" option in the block configuration doesn't even stick when saving. I checked the configuration for the block itself and that value is set to "FALSE" even when I just saved it turned on.

How to test it? Can you explain?

Create a menu, add the block using superfish, enable "Expand all menu links" and save. Setting is not saved/loaded.

Having the same issue. Checking the box for "Expand all menu links" in Menu levels settings section of the Configure Block for my superfish menu, has no effect upon save. Opening the Config back up again show the box as unchecked again. Not possible to save the block with this box checked it seems.
