Because they didn't compile it with the new FDG.
The FGD has nothing to do with it. An FGD file is not even required to make a map, much less compile it.
I'm quite sure it was due to the whole clipping tweaking and fixing n what-not because now, the old official maps (ESF_Cell_Day is a good example) has a few major clipping issues.
Also, it may be because the old official maps do not measure up to the quality of the new official maps and they didn't want to bother remaking the old ones.
I personally love the new maps, except that my FPS goes to **** (From about 113 FPS to 50FPS) on them (Mainly just ESF_Cell_Games and ESF_Cell_Games_Night)
