personal page with my product collection have a incorrect toolbar navigation

i have create a new cms page, in this page i connected a block with a personal product collection. The list of product is shown correctly in front-end but the bottom toolbar for navigation the product collection page show the number of total page. example: my site contain 900 products, and are visible in 90 pages. in my personal page i have only 25 products (correctly viewed), the toolbar navigation contain 90 pages instead the 3 pages of my products.

In this case, the collection size(number of product per page) is configured wrong in your navigation bar. You should configure it have the same value as magento system.
