Show mobile menu on higher resulution

Hi Folks, and thank you for this great theme. Meanwhile i own over 8 licences because of the great support and functionalety!
However i have a small question.

i altered the mobile menu so it would show up sooner (on a higher resulution with this code:

@media only screen and (max-width: 1360px) {
#mobile-advanced, #advanced_menu_toggle, #advanced_menu_hide { display: block; }
nav.main_menu { display: none; }}
#wrap_all {
position: relative !important;
}

Which works fine so far.
Unfortunatelly when one first visits the page the mobile menu shows up on the right side of the boxed layout (see screenshot https://gyazo.com/a48a58808a24dcb6a4bda8a20d8208cf )
Once you open it and then close it it disapears. so how do i fix this?

Thank you very much
Kind regards
Joschi
