BIM4Struct v1.3.0 on Dynamo 2.1 rebar layout node not working

Hello, I am trying to automate my rebar drafting on Revit with the help of BIM4Struct, Dynamo for Rebar based on a webinar from Autodesk:
“Dynam(o)ite Your Rebar Design”
Dieter Vermeulen - Autodesk
Link: Dynam(o)ite Your Rebar Design

I can’t seem to set rebar layout rules. The script runs but no new rebar is made. Do I need to get a specific package? Thanks in advance!

Anyone a solution for this, ive got the same problem
