Unable to set National League North/South fixtures?

I've added the fixtures and results down to National League N/S, (PL, Championship, L1, L2, NLP all working fine) but the North/South fixtures aren't changing whatsoever, neither results nor fixture lists, has anyone else had this problem? Any ideas if so?

I have the same problem really annoying. Fixtures work but the results don't.

Really frustrating, wanting to start the season in January for a challenge to see if I can turn a season round but a bit hard when I can't change the results to that point :/

It seems like the problem is with the leagues with sub divisions had the same problem with the scottish highland and lowland leagues

Irritating, not sure if it's a way they're hardcoded or if they're just marked as not important so it doesn't work or something on the backend.. hopefully they fix it for 19 as I seem to remember having the same issue on 17 too
