Featured Posts on Homepage problem

Hi everyone,

Just after updating my WordPress, I’ve noticed some problems during editing and publishing posts on homepage. My site is BlogFCB.com, and right in the middle, below “Publicystyka”, are fitted featured posts. I’ve marked them via “Featured posts on homepage”, but now I cant do that. After pushing “Publish” it is still unmarked, and post doesnt appear below Publicystyka, as it had been before.

Does anyone know what is the problem?

Best regards,
