I just realized that both Montpellier fields miss their name and identification ... strange as small fields all have their names. Really not important for me as I am based in LFNG... The name and identifier appear when the pointer touches the symbol.
Same problem on the Ipad.

We don't pick and choose which airfields get their labels displayed on the map, it's an automatic process. If you choose both name and identifier you must accept there is a higher chance of there not being enough space to show the label. That is what is happening here. Zoom in, and you'll probably see them appear.
