Hey there @binok!
In order to show the category in the Breadcrumbs you first need to enable this.
You can easily enable it by logging into your WordPress administration panel and then go to:
SEO -> Search Appearance
Here make sure you have enabled breadcrumbs and under “Taxonomy to show in breadcrumbs for content types” choose the “Category” taxonomy for products. Click on “Save changes” and everything should work perfectly.
