[Plugin: WP Archive-Sitemap Generator] Plugin causes duplicate Content

Hello,

I use custom parmalinks like domain.com/archive

My first page of this plugin looks like: /archive
If I navigate to my second page, the URL looks like /archive?page=2
If i navigate to my first page again, ther URL look like /archive?page=1

How I can solve this?

Is it possible that I get excerpts (22 words) from the links?
Google doesn’t like only links on a page.

Thanks!
