Addendum: Also with the P3D default Mooney Bravo no glidepath is available for ILS 06 and 24 in FSDG Durban scenery. LOCs are perfect on both runway ends.
In the default scenery - after setting FSDG Durban to "non active" - both ILS 06 and 24 cannot be captured at all. This was found with the PMDG 777 and the default Mooney Bravo. The aerodromes VOR is still available though.
