Tracks in a wrong category - displayed as "Extras" after adding other tracks.

[abrimaal]

Some tracks, when added to Race 07 change categories of other tracks.
These tracks are: BATHURST2006, LagunaSeca_v12, Marrakech 2013, Oval1M, Santiago, FVRSydney, Watkins.

The first one is Macau. After adding any of these tracks listed above, Macau is displayed as Extras.
When I move Macau out of the game, then Macau_2007 is in Extras and so on,
it refers first to the original WTCC Tracks.

When these addon tracks are deleted from Locations, everything returns to the proper order. Macau is again in the correct category.

I have already changed in .gdb files of the original tracks, as it is recommended
that the GrandPrixName = EventName
GrandPrixName = Macau 2006
EventName = Macau 2006

Adding any of these tracks listed above still change the category of Macau to Extras.
I have viewed .gdb files of these tracks, I see no major syntax errors, such as inequal number of brackets, comments without //, merged lines without new line...
I have also written a new .gdb file for one of these tracks using a good .gdb file as a base.
The tracks still move other tracks to Extras.

They are playable, but I want to get rid of this bug and I really don't know what else can I do.

Got it. There are more .trk files than .gdb in the track folder. Usually this is _output.trk from an editor or a copy of the .trk file.
