I have not had this issue in the past, I just recently updated to the Dynamo 2.0.2 but do not see why I am having the current issue. I am trying to set the default value of a Keynote to #, but within Revit it is always setting it as 2. If I do # plus anything else (#-#, #1, etc.) those come across as what I set. Dynamo shows with the GetParameter as it being # but it is not.
I just did a check and it works correctly in 2018 but in 2019 does what is shown in the image.
