Hello,
Do you use any third-party plugin for the variation swatches? Because it looks that issue comes from the plugin styles https://prnt.sc/26io255
So, contact plugin author about this.
You can fix that by custom code in Theme Options > Custom CSS
.template-container .vi-wpvs-variation-wrap.vi-wpvs-variation-wrap-vi_wpvs_image_design .vi-wpvs-variation-button-select {
width: auto;
height: auto;
}
But it would be better to contact plugin support.
Regards
