Infinite scrolling not working with filters

Hi,

On this page: https://arcadesnackdev.wpenginepowered.com/product-category/snacks-mixes, when you select a filter like “Nut Mixes”, it shows correct number of results, but when you scroll down, it’s showing products which do not belong to that category. I’m using an another plugin called “YITH Infinite Scrolling”, and they’ve confirmed that there’s nothing wrong with their plugin’s configuration and setup in this case. Can you please help what I’m doing wrong here.?
