Faceted Search Error: Price Bar and Product Duplicated

[dongholetam]

Hi everyone,

I'm using Prestashop 1.7.5.1 and facing 02 errors with Faceted Search ver 3.0.2 ( I tried to upgrade to ver 3.4 but still the same)

1. Price Bar

https://dongholetam.vn/trang-chu

The Price Bar is stuck at 999.999 to 1.000.000 as attached pictures

And Sort Price Low to High/High to Low has wrong result also (Price is not sorted correctly)

2. Products are duplicated between pages

Between Page 1-2-3-4.... some products are duplicated (repeated) - apprear 2 times in different pages 

For ex: https://dongholetam.vn/seiko

Some products apprear 2 times as attached pictures --> so, some products cannot be shown, Products are not repeated anymore if sorting

 

Many thanks and hope someone can help
