Thanks Bran - I wound up uninstalling DMN and NPW and reloaded NPW using the hard disks. The reloaded NPW still had 320-man units, but it allowed me to access the unit size input in the Options menu, which I was unable to do before. I set it to Ultra, which translated to 160-man units in NTW, reloaded DMN, and using MP setting was successful in re-acquiring same in DMN mode.
Regarding Beta, many thanks to Darth, you, and the others for your continued efforts to improve upon an already incredible mod. I plan on sticking with v2.6+++ for awhile. My only comment would be to return artillery (both round and canister) to the effectiveness it had in vanilla NTW - I don't even bother raising howitzer units using v2.6+++ - more likely to hit my own men than the enemy's. Cheers.
