I see you have used the EA standard way of organising the Activies which are auto-generated from the Structured Scenario.
If you want eaDocX to document this ‘as-is’, then :
1 – make UseCases print their Children (your top-level ‘…Activity_Graph’ activities
2- Create a profile entry for Activity, which you must print INLINE, as you want to print the Diagrams for each one, as well as their Children.

This produces a fiarly bad-looking document, as all the Activities – top-level and leaf-level are of the same type & stereotype, so both print in the same way.

BUT, if, like us, you just want the diagram, then move the diagram to be a child of the Use Case (which I think it really should be… ), and don’t print Activities at all. That way, you have the Structured Scenario (usually with a table of Scenario Steps), then a nice diagram. No point printing the generated Activities, as they just repeat what is in the Scenario Steps.
