I’ll have my coder try that but keep in mind, that most of the people that use this plugin (or any plugin) are not coders, you should really update the plugin and roll out a new version.
A quick fix is to give the option to remove the brand name from the product page, this way we can have a clean product page again. I tried adding this code
table.wp-list-table th#taxonomy-yith_product_brand {
width: 10%;
}
Which made no difference
