Hi Ashleigh,
Thank you for your report. It seems you have an incompatible package on your system, which disabled our 3rd-party navdata.
Do you have a 3rd-party scenery installed? When yes, which one? Have you tried this FAQ?
As you mentioned, the procedures are visible/selectable in Fenix, PMDG, … The procedures are also available in the MSFS navdata package, but another package on your system overrules the data.
Please follow the steps in the FAQ exactly and let us know your results.
Thanks
Richard
