Extremely dark matches, no lights and always rain!

Hi,
i have a strange problem with FM 21. I am playing a save in Czech league and for some reason each match is extremely dark in the match engine and it is always raining in each match no matter if its summer or winter. I am now close to finishing the first season so many matches played so it cannot be coincidence.
I also noticed that the stadium floodlights are always off in league games but if i play friendly match even with the same time of match start, the floodlights on the stadium are on and it looks nice and bright.
Is there anything i can do in the current save to make the matches brighter so it not kills my eyes and i can actually see something on the pitch?
Somehow edit the weather? force the stadium lights to be on? edit the brightness? anything?
thanks a lot
PS:i should add that i am using custom database that expands the lower czech leagues, can something like weather or use of stadium floodlights be wrong in the database?

Have you tried downloading the correct weather region patch? I have and have noticed a difference in the weather from the standard game. Not sure if I downloaded it from here or FM Scout but would suggest you do that. I am not sure though if it requires a new save. It may well say on the download guidelines.
