Hey,
I suspect that when the node converts from Dynamo to Revit elements, it is setting ToDSType(False) in the transaction, which means it is still bound to Dynamo… I tried a script which set this to True, but it didn’t seem to help. Closing and opening Dynamo was the only way for me to break that connection.
Instead I took the method in this thread and swapped it around… It seems happy enough doing different curves in the same graph now…

Hope that helps,
