Unnatural weather changes

Hello, I bought fsrealwx from simmarkt and use it, in fact, I like fsrealwx more than active sky, but the fatal disadvantage is that the weather change is too much, and above all, I cannot use weather radar in pmdg...Do you have any future update plans for this part? (I using p3dv5)

For FSX/P3D choose the weather mode "Weather File".
Unfortunately, PMDG has not opened up to other weather providers. Some requests were unsuccessful.

But when I switch to Weahter file mode, no clouds appear...How do I fix it?

Did you set the path of P3D in FSrealWX?
Dynamic weather set to zero?
