Yes, I know that way. I can Remove all categories except the accessories category. As you can see from what I attached here, there is no “Remove” option in the accessories category, and you can notice a question mark in that category which is not in the other categories.
Is this a bug? or can you explain why there is no remove option in the accessories category?
As you know, by default WooCommerce allows only one Category to be selected as Default Category but you can switch the Default Category among your Site Categories using the row actions underneath the category name. Then In this way, the Default Category can be deleted as it is no longer the default: https://ibb.co/1LzHjSD
