This is a somewhat common problem when sub-tracks have similar names. There is some other track in your list that is disrupting the grouping of the tracks inside the main Zandvoort header.
Then i don't know, that's what happens to me: In your screen Zhuhai comes before Zandvoort and not after as it should, so everything here is strange.
I have THREE Zandvoort entrys!! Must be a "Sort by Tracks Bug" Subscribe - not subscribe did not work for me too...
davehenrie answered this in the second post. Either find and remove the conflicting track(s) or leave it. There's no fix with the current UI.
Hmmm strange thing to be worried about! Did your Rfactor stop working? I saw that but noticed the versions were the same and continued on as normal
Yes, I did point this out. But over the years, I have met via forums and online and such, many many compulsive users. Stuff like this is like a pebble in your shoe. Yes you can keep walking, but you don't enjoy it as much. I hope, as stated above, perhaps the new UI will fix this. Otherwise, my suggestion would be to create a list of conflicts. We know VIR suffered from this and others. Perhaps one of my compulsives can begin to investigate.
