Assembly from elements Clockwork output

Hey guys,

Ive used the clockwork node assembly from elements for some time now and it always worked perfectly. Just recently I started using revit 2021 and it looks like the node creates the assemblies but doesn’t give them the correct name and doesn’t give the correct output. This only happens when creating multiple assemblies. When creating just one it works perfectly.

Can someone help me or has someone else already seen this problem?
