Hi pmorenogarcia,
As you say, 03-21 runway is probably the old denomination of the current 02-20 runway. For some unknown reason, when a runway changes its denomination, sometimes, somehow, the runway is duplicated in apt.dat
Duplicated runways happen at least at two airports in Spain: LEJR-Jerez (already reported:
viewtopic.php?f=5&t=39046 ), LEPP-Pamplona (also reported:
viewtopic.php?f=5&t=38884 ) I'm sure this also happens to other airports in the world: a similar issue was reported a couple of days ago at Santiago de Cuba. The fix is not only removing the line in apt.dat, the scenery must be rebuilt to prevent the duplicated runway to be drawn on the scenery as well. Indeed, if you look closely, there are two runways at LERJ one on top of the other!
There are things that are easy to change in the FlightGear community, others not so much. Changing the apt.dat file, even a single line, is one the the hardest things because so many other parts of the project and other projects depend on this file. The community seems to work like "the apt.dat file changes only once in a decade"
Of course, this affects only to the "official" FlightGear distribution. You or your university can distribute a custom scenery for LEJR. In fact, WoodSTokk provides a complete fix for LEJR:
viewtopic.php?f=5&t=39046#p384875 . As you can see, it involves much more than a single line. There was a time when I provided a custom scenery for the whole Iberian Peninsula, because so many airports suffered from issues similar to this one:

Creating buildings does not imply changing the layout of the scenery, and seeing your buildings accepted in the database is a much faster process (days!)
