Faceted search displays attributes only with more than one item

[Oehler]

In faceted search an attribute won't display until there's another item of this attribute in category view.

 

Example: 

 

If we have an attribute called: size with the options: M, L, XL

 

When we open a category which has only products with the size of M the attribute "size" won't display in the faceted search. It only appears if we have products with M and also products with L or XL

 

 

Do we have a solution to display the attribute, althought there's only one item in the selected view? 

 

 

Thanks for help 

 

 

 

 

 

In the faceted search filter this attribute won't display until there's another item for this attribute.
