Abrupt change in barometric pressure mid-runway SPJL

[feebleraven]

ISSUE DESCRIPTION

Description of the issue:

There is an abrupt change in pressure on the runway at SPJL. At runway 30, the pressure is 1022, and on runway 12 it is 1035, which is a large difference. The METAR shows 1035 as the pressure. This is a serious problem in my opinion. This problem hinders approaches to this airport, but I didn’t only notice this problem at this airport; I also had problems with the live weather at SPHO, SPJR, and SPJJ, where it interfered with my private RNAV approaches.

This also happens in the default scenario

Can replicate but noticed a weird behaviour:
Using C172 G1000, Live Weather, METAR reports 1035 HPA.

Can replicate.
If spawning RWY 30, indicated pressure is 1018 (don’t know where it comes from). Using the “Set Altimeter” binding, pressure is correctly set to 1035:

If spawning RWY 12, indicated pressure is automatically adjusted to 1035, no action required:

Spawning RWY30, pressure should be automatically set 1035.

Additional testing and weird behaviour at this airport.
Live weather, Metar reports 1034 HPA.

When launching the sim and spawning for the 1st time RWY 30, altimeter is correct but pressure incorrect (1013). Using “Set Altimeter” does not work:

Spawning RWY 12, altimeter/pressure are correct:

Spawning again RWY 30, altimeter/pressure are incorrect:

Using “Set Altimeter” does work this time :
