Weird cumulus clouds appear above 30000ft - XP11

Note that I'm using latest FSRealwx + latest XPRealwx
This bug (or may not be a bug) appears when i set weather mode to Direct. As you can see in the image, there is a few cumulus layer at very high altitude. I don't have any image for these cloud while flying in game but i can say the cloud is really dense and large. I think this is unrealistic and pretty annoying.You may ask why i don't use weather file instead. It is because there is another issue regarding how xp11 visibility behaves in weather file mode:
Example:
Metar: visibility 9999 which means xp11 will read it as somewhere around 10sm. As a result, the clouds become unrealistically dark
Back to the main topic. I hope developers can see this report and begin to fix either direct mode or weather file mode.
Thank you. 

Hello.
Yes, I'm reading along
Actually, those should be cirrus clouds.
I'm currently revising XPrealWX because of changes in XP12.
I'll fix the cloud bug with XP11. Please be patient for a moment.
