Hello,
Sorry to say but we can’t seem to understand your concern.
There isn’t such a Tab that comes already under the Theme, we can’t seem to find it. Here is one of the Products from Test Site: https://blackpearlspro.com/woodmart_support/product/henectus-tincidunt/
Can you please elaborate more on how this Tab is coming on your Site? And also please share the Site WP-ADMIN Login details too so that we can check this on your Site and assist you accordingly.
Best Regards.
