So that's resolved, thanks.
One other thing I noticed while checking this, and comparing to VST with multiple outputs: the i/o options are different for LV2. VST has several more features including the newest i/o stuff added to that area, while LV2 doesn't (but also has "LV2 advanced routing" greyed out). It's not critical to have all these features for LV2, but if they were forgotten to be added, figured I should mention it.
