C1 10.1: Regression in Process Recipes (Sub Name)

Previously, when I had "Sub Name" token in the Sub Folder field of Output Location portion of the recipe, I could specify simple dot in the "Sub Name" field of Process Recipe -> File, like this: .

That meant: use the Destination Folder directly, without any subfolders.

With C1 10.1 the behavior is changed, now the dot means: use weird subfolder named EmptyName! Which just breaks my exports and their locations.
