Customized values don't show in filters?

[Karakko]

Hello, I'm using PS 1.7.2.1.

 

I've added 5 products, all of them have prices set to around 1.5 €. All of them define four features. "Compositions" and "Colors" use pre-defined values, "Height" and "Width" are customized values (e.g. "112 cm").

 

For some reason the customized values don't show, even though they are different. How so?

Also, is it possible to modify the list of price ranges for the "price" filter?

 

Thanks.
