I have visited your website. It seems that you have added the same product in both the categories that’s why the product is displaying the other category breadcrumb.
Please make sure that you have added the product in only one category that will fix it.
The categories products and categories are controlled by WooCommerce and our theme doesn’t influence them.
It is the default behavior of WooCommerce when you use multiple categories for products. Unfortunately, there is no option in our theme settings for that.
You can use any third party plugin that better meets your requirements.
