Woof per Page

Hello,

I am using Woof Product filter via AJAX which is working great.

I have a custom per page dropdown, which adds this into the URL and displays more products, but when I click on the second page Woof ignores the per page and therefore shows me all the pages again.

Is there a way round this?
