Admin layout is not correct

When I am in the admin, the side menu is running into the main page. When shrunk down it is ok but on full page it is not correct. 

Please find following lines on script >> assets >> css >> script_styles.css on line 191 and replace with next code.

.jquery-accordion-menu {
    min-width: 260px;
    float: left;
    position: relative;
}

Replace with

.jquery-accordion-menu {
    min-width: 260px;
    float: left;
    position: relative;
    max-width: 260px;
}

But my suggestion would be to reduce the name of your website, which is stretching the nav bar, You can change My texas Country Dist to shortername this will also solve your issue. You can change it by going to General Settings below your image menu.
