I think there is bug in the filtering in Rapido.
Here is a list with 7 mountain bikes.
If I then filter by "Brand" and choose "Mongoose" i will get 11 bikes.
And if I clear that filter I end up with 180 products.
We have the same behaviour on a site based on Rapido : https://wimab.se/produkter/foerelasningar
