Hi Mahy,

Sorry for the late reply we missed your topic.
To fix the issue that you are having in the menu please go to Appearance -> Customize/Theme Options -> Design Options Tab -> Custom CSS paste the following CSS code and Click on save button:

.container {
    padding: 0;
}
#access li {
    margin-left: 10px;
}
#access a {
    box-sizing: content-box;
}

Thank you!
