Ah thank you, I think I understand now.

This is a bug in 1.8 and 1.9, if a process has no impact assessment results at all (no elementary flows or no flows characterised in the selected method), then an error is shown as nullpointer. This is somewhat annoying but does not affect calculation or other things. It will be fixed in the next latest release.

Best wishes,
