I'm playing on the legacy GIUK battleset running the latest beta files on Windows 7, and using HCDB-150928. I've noticed that the Formation Editor is missing the usual buttons to set sizes and assign units to zones! I've attached a save game, simple scenario, and screenshot in the zip. Pressing F4 on any group in both scenario and save should show the problem. This does not happen on GE 2018.002, BTW.
