Personalized node are not uploaded

Hi everyone,
While trying to use Butterfly on dynamo, i find that all nodes are not charged correctly. (see the JPEG)

So, new user of dynamo that i am, could someone help me ? Where did i go wrong in the installation ?
I’m on Revit 2020, not really sure if that matter though.

Your image didnt upload?

Ive recently tried to start using Butterfly for Dynamo - at first i couldnt get anything to work and it was because of the path that the Butterfly nodes use to look for different python modules.

Did you get anywhere with your problem? I still cant get the OpenFOAM aspect to work.
