Ajax Product Filter problem with Preloader Plus plugin

Hi,

The Ajax Product Filter is blocking the Preloader Plus plugin. The Preloader works everywhere except on the shop page, when I change the price in the product filter, the filter doesn’t change the price and keep showing the preloader.

I use Preloader Plus – WordPress Loading Screen Plugin, but i tried many others i thought it would be a quick fix, but it doesn’t matter which preloader I use.

Could you please assist?
