Change this code http://prntscr.com/10w204d to
.outofstock .content-product .button,
.content-product .st-swatch-btn-readmore {
background-color: grey;
font-size: 0px !important;
}
.outofstock .content-product .button:after,
.content-product .st-swatch-btn-readmore:after {
content: "SOLD OUT";
display: inline-block;
font-size: 14px;
}
.outofstock .content-product .button:before,
.content-product .st-swatch-btn-readmore:before {
margin-right: 0px !important;
}
The label can’t be displayed in this case.
