Well after some more investigation I finally figured the problem out. Inside the 'export_descr_unit.txt' file all the entries under "EB Recruitable General" had their ownership switched to 'slave' only! Don't know how this happened, cuz I certainly didn't do it. Maybe a bug of some kind? Anyway, luckily I had a backup of the original EDU so everything is back to working order.

In the event someone else ever runs into this problem hopefully this solution will help.
