Apparently, the Process Flow option to select an existing label on an instance of the Process Flow in the model is broken:
In the model attached, the processor instance, a stock "Basic Processor" Object Process Flow, has a label "ProcessTime". It is correctly used in the delay activity, when typed in manually, but it can´t be selected from the pick list options. This is for at least 20.2.3 and the 21 beta.

BTW: The Process Flow Objects still use the "old" GUIs.
