problem with class CSS module dark

Helo,

I have a problem with przyrostek class CSS module: dark, in category module in e sport. I changed it to light for a while, and latter changed it back to dark, but light still is there. I cannot repair it.
I wish to have dark box with my category in shop.

Can you tell me what is wrong? I cleared joomla cache nad it dosent help.

Thanks for help.

Please make sure that you use space before suffix name like ' dark' not 'dark'
