Problem with Metaslider

Hello guys,

I’ve got little bit problem with menu on my sites.

Site is http://test.fintele.cz

I’m trying to use plugin MetaSlider, but everytime I create slider and put it on my site, it’s “overflowing” – dont really know word (translate.google says “overlap”) over my menu(https://imgur.com/a/39gFn). Is there any way how to fix it so when i scroll my page down, my sticky menu will “hide” this slider?

Thanks for any help 🙂
