Layered Navigation block - after refersh disappear the filters

[szanaszabolcs]

Hi,
 
First of all technical infromations:

My Prestashop version: 1.6.1.7
Theme: Deafult-bootsrap
Module: Layered Navigation block (Ver: 2.2.0)

And my problem:

 

On my webshop at category page i use the layered navigation module. I check some filters and everithing works fine. Now i have some filter checked and i refresh the page the filters are disappear (usually only the color remains). 

(OR i see one of product page and i click back at the browser on the top the filters are disappear too.

 OR i copy the url and paste it new tab  the filters are disappear too)

 

everyone else is working well?
