Why bxslider is conflicting with the css filter?

Good day!

On the website bnews.kz/ru added css filter to everything on the site was black and white. But now there is a problem - when you hover over the slider with main news, then instead of white screen.
If you disable bxslider code, then no such problem.
Can someone tell me how to get bxslider to avoid conflicts with the css filter?

Actually, I really like the sites devoted to our country ,I, too, Kazakhstan.
But guidance checked all the sliders and the described behavior is not seen
