No way to Create Nozzle for Existing Printer?

I purchased some of the MicroSwiss hotend/nozzles and want to create a custom nozzle setting based on my observations from calibration prints.

I selected Create Printer/Nozzle for Existing Printer and then Select Printer (Bambu Lab X1 Carbon) and Nozzle Diameter (0.4 mm).

However, when I select OK, I get an error message:

I do what is requested but get the same error each time.

I saw someone had this issue before, months ago, and I am wondering if it still is not possible to create nozzle for an existing printer or if maybe someone might have a workaround.

Any ideas?
