Crawl errors page not found

Hi Guys

Ever since moving to Yoast i get hundreds of errors in google with pages not found.

Here is an example

http://www.kimboscakes.co.uk/tag/suprise?paged=7

For some reason there is a ?paged7 or other page number being added at the end of the tag word suprise.

it should read

http://www.kimboscakes.co.uk/tag/suprise

how can I prevent the ?paged from being added pleaae

Any help greatly appreciated
