Weather downloading other airport than the current one

Hi, guys

I bought the app recently and found some problems when downloading weather. 
I often fly SBSP/SBRJ with MEJ like B738 and A319. The problem always occurs when operating in SBRJ. 

SBRJ is 10nm away from another airport: SBGL. However, even when departing from SBRJ in the simulator, with the plane currently in SBRJ ground, the program still downloads the weather from SBGL. 
It looks like it refuses to download from SBRJ. 

Rarely it downloaded correctly from SBRJ. No matter which source i choose, all the three sources behave the same way. 

I'm using P3D v3 and v4.5, fsuipc updated in both of them. 

Is there any way we could change this so the program can download the actual airport weather file?
