Stoermelder Transit,+T not working

Hi gang, I got this issue with the +T expander for the Stoermelder Transit module. When assigning/writing to any empty +T slot, it later appears as if unwritten(grey) and cannot be selected/recalled. Anyone else experienced this? Im using packone 2.0 beta3 with VCV Rack 2 2.3.0 on a Mac mini running Catalina.

Please refer to the user manual. The active number of snapshots must be set by a long press on the last slot.
