Hello,

I added this code into Customize > General > Custom Codes > Custom Css:

.woocommerce .quantity:before {   right: 75.5%; }
.woocommerce .quantity:after {   right: 75.5%; }
.tawcvs-swatches .swatch-label {  width: 50px !important;}

This is the result: https://postimg.cc/image/g2gja56k7/
I don’t see the previous code here. Were did you add it? Do you have removed it already?
Let me know.

Best regards!
