PPP working only on first page

Hi,

I’m having problems with the PPP when navigating through shop pagination. If i select for example 64 products per page and navigate to the second page, it goes back to the default 16 PPP. I tried activating “First category page” option, changing to Twenty Seventeen Theme and deactivating all plugins except this and Woocommerce and i’m still having this issue. Have you found a solution to this?

Thank you
