Template not working for attribute pages.

Good afternoon Varun,
I have checked the woocommerce/templates/taxonomy-product_cat.php is correct and in place, but my main template is not coming across to pages defined by attribute.

For example:
Page assigned by category: https://demo.davelindley.com/product-category/honey-onyx-collection/
Page assigned by attribute: https://demo.davelindley.com/pa_color/brown/

If you have any ideas what could be causing this I would appreciate it.

Regards,
Dave.
