[LSGS/Sion] PAPI incorrect angle

Are you using Developer Mode or made changes in it?

No.

Brief description of the issue:

It seems the PAPI of runway 25 (I have not tested runway 07 yet) at LSGS/Sion airport is not at a 4 degree angle (see chart excerpt below), but much steeper. I suspect it is set to the same angle as the accompanying IGS approach runway 25 which features a glidepath angle of 6 degrees. The PAPIs for both runways are, however, set to 4 degrees, because that is the descent angle for the visual portion of this approach.

Detailed steps to reproduce the issue encountered:

position your plane onto the runway 25 axis at an altitude of 2500 feet at DME 4.4 before SIO VOR and check the PAPI-lights, they are all red.

Build Version # when you first started experiencing this issue:

latest and all previous versions when I flew to Sion. A friend, flying the same approach just before me, reported the same issue in his MSFS, also latest version.
