Description Of Issue

Previously hidden albums are no longer hidden since updating to B778. I have a number of system-type files used for tests and calibration that I never wish to see in Albums view but they now appear since the update to B778.

I’ve tried hide/unhide/hide, restarted and cleared client cache and restarted core.
