Why does this problem occur with this airport using Live Weather?

I’ve had this problem since the simulator came out. I reported it a year ago, but no one paid attention to it. Now I’m back to posting this here. I consider it a BUG with Live Weather or with this area. I’ve tested with both the default and third-party airports, but it’s the same in both cases. I tested and recorded video with Active Sky and Live Weather. With Active Sky, the RNAV works fine on the vertical approach, but with Live Weather, the RNAV behaves very strangely, taking the aircraft very low over the glide slope.
This RNAV isn’t set to the airport by default. It’s a private RNAV, and I didn’t build it.
Asobo, could you please explain to me what’s going on here?
Is it a pressure issue?
Or what?
THE AIRPORT IS “SPJL”
I also tried it with PMDG, same result, and with IniBuild A320, same result. I also tried it in 2024, hoping they’d fix it, but no, same problem.

If anyone also has this problem with other airports, please report it.

with active sky

with default live weather
