Faced Search Addon

[pcFrogRo]

Hi all, 

We are having some small, but annoying, issues with Faced Search Addon. 
We can take by example Laptop category in our online shop. 
Search filters are on the left. If you choose by type of the processors, i5 (just an example now), Faced Search will show all laptops with i5 processor. 

The result will be https://pcfrog.ro/13-laptopuri?q=Procesor-Intel+core+i5 / All good at the moment. 

The problem will appear when you want to add the second filter. We will add a 256GB SSD. At this moment the link is like https://pcfrog.ro/13-laptopuri?q=Procesor-Intel+core+i5/Capacitate+SSD-256+GB 

So, we are looking for all laptops with i5 and SSD 256 Gb. 

At that moment filter will show all laptops which have SSD 256Gb, doesn't matter if is with Intel Core i3, Intel Core i5, Intel Core i7 or Intel Core i9. All laptops will be shown. 

Someone who encountered this error and how can be fixed? 

Wish you all a legendary weekend.
