Hello, @TFS,
In order to solve your issue simply go to the Dashboard >> XStore >> Theme OPtions >> Theme Custom CSS >> Global and then paste the below code at the bottom of the CSS box there.
.single-product span.posted_in a:first-child{padding-left:0px !important;}
Then save settings and check back to your site after clearing the browser cache. The result will appear like this: https://postimg.cc/4KxGhY08
