Hello, @Filips,
Unfortunately, there is no such option to simply turn it OFF using Theme Settings.
So you have to edit every single product category and remove the “Description after content” from there as per your requirements.
OR
You can use the Custom CSS listed below, under XStore >> Theme Settings >> Theme Custom CSS >> Global CSS, to remove it from your site.
.term-description.et_second-description {
display: none !important;
}
