Hi Florian,
the reason is, that ASOBO makes an 1:1 reference to the runway-ident. In this case you have runway 2 instead of runway 02. It´s the same, yes - but it seems that the sim compare the runway idents and when they are not 100% equal, the procedures will be suppressed.
As in this case: All procedures for 02/20 are suppressed - therefore you see only the BERNI and CHRISM SID because both are only valid for 13R/31L. In no FMC you can enter 2 for runway 2, you must always enter 02, so it´s impossible for us to know, which runway has a leading zero and which not.
In my case, this is a bug in the sim because again, no FMC nor Garmin allow you to enter only one letter for a runway. Sorry Florian, but I would report this to ASOBO.
Cheers,
Richard
