Hi Emanuel,
Please try the same with any default/stock aircraft, like the C172 with the G1000, first. This should always be the first reference to check if this is an addon issue or any other issue.
I have checked the data and also your example in the default G1000 (MSFS2024), AIRAC 2602 installed:
The procedures are included, and I can also select the departures correctly.
Not sure about your system; have you installed any 3rd-party scenery? When yes, this link is HIGHLY recommended:
FAQ - MSFS2024 (SU3 and above) - airport, procedure, waypoint, 3rd party & flightplan import issues
In most (nearly 99%) of such “issues,” there is an incompatible package on the system, the culprit.
Cheers,
Richard
