Hello, Kjeill.

The following styles should remove the borders in question:

html .RadPanelBar_Material .rpFocused {
    box-shadow: none;
}
html .RadPanelBar_Material .rpExpanded.rpRootLink {
    border-width: 0;
}
html .RadPanelBar_Material .rpExpanded.rpRootLink + .rpSlide > .rpGroup {
    border-width: 0;
}
