Hello,

I saw the screenshot you attached.

Please try adding the following Custom CSS in the Global Custom CSS area under Theme Settings >> Custom CSS.

.variations_form .variations label:after {
    margin-left: -3px;
}

.variations_form .variations label {
    margin-bottom: -8px;
}

.swatch-on-single:not(:last-child) {
    margin-right: 10px;
}

Best Regards
