PCG GPU Custom nodes

Hey!
I’m currently working on some PCG tooling for the studio I work for and in an attempt to improve performance, I wrapped many nodes of PCG GPU inside subgraphs to reuse them. Problem is, the CPU upload arrow shows if I don’t add a point processor after it, is it a display bug? Is it normal?

Thanks!

What the subgraph looks like:

And the compute source content of the point processor:
