Please, do not send you support request in PM.
It's not a privacy problem, it's because your issue and the related solution could be helpful to other users in the future.
If you send me a PM, I will ask you to post your request on the public forum.
Now restart X-Plane and try to apply the seasons as desired.
Stop the simulator.
Post a support request on the dedicated forum thread, explaining your problem and attaching the log.txt file.
Note: you can find the log.txt file on the X-Plane root folder
Without the log.txt file I (and others) cannot help you.
No file, no help.. simple as that.
