The PO does not seem capable, at all of using the super-river crossing units assigned to it in this scenario. This is one of the only scenarios in the game where the AI MUST cross a super river and use the bridging units.

I've already played around with the formation orders and changing the ownership of the super river. Nothing works.

Yeah this was reported, and deemed not quite a bug, but an oddity brought on by the changes to the PO in the new version (making it highly risk adverse to exposing engineers):

So they came out with an updated version with the bridging units already in place over the canal.
