When I make a product system of a process consisting of several product flows as input (connected to a respective provider) and output consisting of my final product and waste flows, the model graph doesn't show any of my inputs and outputs other than the final product.

I have tried creating the product system with default providers, without default providers etc. etc. and nothing works. (I have gotten it to work before but it seems random when it works and not, and I can't repeat it)

Do you have any idea of what I'm doing wrong?

The model graph shows only waste and product flows, and takes the information from the database - maybe your other flows are all elementary flows, or you didn't save the process, or didn't refresh the model graph after you saved?

If you want, post a picture of the process and the graph (edit the question), thank you.
