How to change permalinks for vendors

I want to have vendor permalinks that are good for SEO but don’t reveal the identify of the vendor so I change them on the vendor page but then they change back. I can’t find what triggers this. Is it a known bug? How can I stop this happening?

Hi,

Please provide more details. Did you manually change these settings? Please note that permalink is always reset to username or attribute if you have assigned it as a vendor name source (in the vendor settings). Username is used because it is the only unique value in WordPress for users, and it cannot be manually changed in this version.
