Missing header bar in desktop and no buttons in mobile

[adrianovsky]

Hi, I have a issue with the header of my store.
1: The top white part of it is fading out making the user browsing the store unable to move to the search bar or their account quite quickly.
2: Here is the situation regarding the mobile version. The header is static and does not move making it impossible to expand the main menu at any time and as in point 1 - there is no white bar either.

Could someone help me with these related two issues?

I have dealt with the first issue, however, the second one still remains. Could someone please help me?
