Brands SEO issue

Hi,

This is kind of hard to explain I’ll try my best.

https://HIDDENDOMAIN/brand/ANY-TEXT-HERE/BRAND-SLUG-HERE/

So, basically you can add any text between brand/ and /brand-slug-here and it will show properly the brand page. The issue with it is that google crawler is constructing a lot of weird URLS like https://HIDDENDOMAIN/brand/john-doe/BRAND-SLUG-HERE/ or https://HIDDENDOMAIN/brand/crazy-text/BRAND-SLUG-HERE/ and it is affecting a little bit my website SEO.

Is there a way to avoid this behavior?
