Header/menu Issues

Hi all.

I have some issues with the menu in my wordpress website.
could you please give it a check and tell me what i have to change in the stylesheet or elsewhere to solve my problem.

There are 2 issues:
– the header is probably transparent so if i but it blocked, than scrolling down it is barely visible;
– there is a blue bar in the menu name tags that should not be there but can’t figure out how to take it away, or make it transparent.

Thanks a lot for help!!!!!
