Menu block added space

Hello there, not sure if I am posting this in the right place. I was wondering if you guys had a solution to this issue.

When using the menu block and switching between the different menu sections, a space is left open at the bottom of the block. If you have an idea on how to fix this or have a form that has answered this, please let me know. 

Thank you!

.menu-section-header .menu-section-title {
    background-color: #8DC73F;
    display: inline-block;
    padding: 5px 10px;
    font-size: 22px !important;
    line-height: 1.2;
    font-weight: 600;
    text-align: left;
    color: black !important;
}

.menu-items .menu-item {
    margin-bottom: 20px;
    padding-bottom: 8px;
    border-bottom: 1px solid #e9e9e9;
}
