I'm having the same issue with another file, where I cannot find the options to edit or delete the conflictive parameters... I could fix the parameters on "Sink Fixed.rfa" but I cannot fix another file that has the same issue, because there are no delete options on the family type dialogue box.
the name of the other file is "Sink.rfa" I'm going to attach on this reply too. try it out and you will see there are not delete options on this other file..
The icons from the image below are from "Sink fixed.rfa" but they do not appear on the family types dialogue box of "sink.rfa"

This is on "Sink.rfa" there are no edit parameter options. I attached the file on this reply, it is another family with the same issue of the parameters but I don't how to delete them cause there is no option.
