trail labels, element type

I’m making a map using OSM, mkgmap, my own style and TYP-file.
If I use an element ID > 0x30 for a way/track, the track shows up, but labels do not show up on the Garmin Montana. They do show up on qlandkarte. If I use an element ID < 0x30 it works. The style manual says that the id must be less than 0x3F. Anybody know what might be going on?
