Hello Martin, I used to have this kind of problem before. Not sure if I resolved it with the help of folks on this mailing list, but I never tested. What you can try is to remove the prio parameter from the classes and leave the prio only for the filters. Let us know if that helps. Cheers, -Nikolay Martin Björnsson wrote: > Yes, exactly.
