The 'Evaluate' attribute is not valid - Simscape masking

I am trying to make a masked subsystem with an integrated Pipe (TL) block from the Simscape Fluids library. In the mask, I promote the 'Cross-sectional geometry' and 'Pipe diameter' properties. Previewing the dialog box works at this point. When changing the cross-sectional geometry in the dialog box from Circular to e.g. Annular, the mask editor gives the following error: The 'Evaluate' attribute specified for parameter 'Parameter 2' of block 'Model/Subsystem' is not valid. Looking at the Mask editor, the entire list of parameters changes. The properties are still there but all the namings are gone. Moreover, I noticed that depending on which property is loaded in 'Cross-sectional geometry', the Evaluate attribute of 'Pipe diameter' is either checked or not, and I cannot change it by clicking in the mask - it seems to be locked. I've been looking for the attributes via command line using get(gcbh), but I was not able to find a way to change the attribute. I found something in the 'DialogParameters' structure, but this is read-only and cannot be changed using set_param.

Is there a way I can get the masking working, with the ability to set both the Cross-sectional geometry as other properties like Pipe diameter?
