Glitches in Default Nodes

Hi everyone,
I’m using Dynamo Core on Revit 2020. I’m also running the script with nodes from Rhynamo and Direct-Shapes packages. I am running into a weird situation where each time I open the script, the input nodes behave as if there are more than one output. I have to recreate the node each time. Has anybody else come across this problem or know a way to fix it?

Many thanks in advance.

Those aren’t default nodes. they are custom nodes and you need to update to the latest version(s) of those packages as there was a bug introduced with Dynamo 2.0 that required a change in package author’s underlying code. The Model Categories node is from Rhythm.


And also Update Revit 2020 to Revit 2020.1 from here
