Hello, @LMcompany,
1- Thanks for the screenshot I have understood your issue.
Now, In order to solve your issue simply go to the Dashboard >> XStore >> Theme Settings >> Theme Custom CSS >> Global and paste the below code at the bottom of the CSS box there.
@media(max-width:768px){.children-align-inherit .et_b_header-logo{margin-top:35% !important;}
span.et-toggle.pos-absolute.et-close.full-right.top{right:0px !important;}
.et-mini-content-opened .et-content_toggle .et-toggle{pointer-events:initial !important;}
}
Then save settings and check back to your site after clearing the browser cache. The result will be appear like this: https://postimg.cc/3WWRTMPy
