Hi @nlopsy,
when switching between the Main Page and the Shift Page with the Shift Button, the last Mode is activated there. This is intended so that you can switch with the Shift Button with just one click, e.g. between any Mode on the Main Page and the value under mouse Mode or e.g. between the Event Mode and the Nudge Mode, etc.
Therefore, this behavior in the workflow sometimes requires fewer clicks on the FaderPort. I think most users are used to working like this.
This behavior should be reprogrammed in the script if it is not desired.
