Bug: Snapshots not saving when opening the Layouts Menu

When I open the Layouts menu, I see the “Now” Snapshot as usual. Up until lately, that would be kept in a list on the right column of the Layouts menu with a timestamp. If I were to open the Layouts menu again 10 minutes later, I would see that “Now” snapshot along with the timestamp for 10 minutes earlier. This is not happening anymore.

Software version: 4.2b SR-1 (4.22.5.1109).
