Make sure you do not have Asobo KORD installed in addition to the FSDT scenery, then uninstall the AIRAC cycle, launch MSFS to reset the scenery file, close it and reinstall the cycle. That should fix it.
This is an issue with the combination of Navigraph/Asobo KORD. Asobo KORD is missing runways, so the sim just doesn't load any of the procedures that Navigraph provides. You can fix it by getting a 3rd party KORD that includes those runways
I do hope we can just use a modifier button for reversers because having to be super careful when going to idle on a throttle with no detents would not be fun
