leisure=track is defined as applying to nodes or areas... in this case you
seem to have effectively applied it to linear ways...
By the looks of it, osmarender at least has probably only rendered it
because of it's features to try to correct broken areas...
Adam, who has already replied has mapped one such that the outer boundary of
the track is drawn and a hole drawn on the inner boundary of the track...
I'd suggest that to correct these problems then the area should be turned
into a contiguous area around the perimeter of the track such that the
'tails' have some actual width and are contained in way and area as the main
oval section of track...
