Pagination in BRANDS section causing duplicates

Hi,

Pagination in brands section is generating new urls for products ending in ?page=2, ?page=3, etc and is causing duplicates. For example in brand SampleBrand page 2
http://www.site.com/SampleBrand?page=2

all products have ?page=2 appended to the end of the url:
http://www.site.com/productOne?page=2
http://www.site.com/productTwo?page=2
http://www.site.com/productThree?page=2
etc
all products on page 3 have ?page=3 appended to the end and so on, and so forth.
This is causing duplicates of virtually all products. Sure enough canonical is in place, but I've got all urls indexed TWICE in search engines and this is causing problems. On the other hand pagination is working just fine in categories.
OC version 1.5.6.4, with seo urls turned on
Would really appreciate if somebody could advise how to fix that issue.

Any thoughts on this are appreciated!

Just disallow /?page in your robots.txt file.

That will cause indexing issues as pagination of categories would be disavowed as well.

Product URLs in categories are generated properly, maybe similar code for manufacturers would do?
