Solution for this topic

Normally, only in this category the product description should be visible, on all the other future ones there won’t even be a description:

Then along with the previously shared CSS code also use the following CSS code.

.type-product.product_cat-prijzen-prijslijst .sh-woo-layout-right.col-md-6 .summary.entry-summary .product_title,
.type-product.product_cat-prijzen-prijslijst .sh-woo-layout-right.col-md-6 .summary.entry-summary .product_title + div,
.type-product.product_cat-prijzen-prijslijst .sh-woo-layout-right.col-md-6 .summary.entry-summary .woo-short-description,
.type-product.product_cat-prijzen-prijslijst .sh-woo-layout-right.col-md-6 .summary.entry-summary .woo-seperator-line {
    display: block;
}
