For anyone else out there who had the same issue as I did:
I opened MapCache.ini (C:\Users\NAME\AppData\Roaming\My Battle for Middle-earth II Files\Maps) and found my maps data:

I changed the
isMultiplayer = no
isScenarioMP = no
to
isMultiplayer = yes
isScenarioMP = no
And now it shows up
If not, just fiddle around with that lol.
