User created Printer presets disappeared from Creality Print

I created several user presets for different nozzles and use them in several projects. Today when I opened Creality Print none of the presets show in the Printer selection area, just one System Preset is there. Has anyone seen this behavior or know how to get the presets back?

I found them stored in Windows folder under user\C:\Users\AppData\Roaming\Creality\Creality\Print\6.0\user\125489617\machine folder. But they do not show in Creality Print any more under the pulldown selection for Printers.
