using multiple attributes variables

Hello,

While using multiple attributes variables for single product, the configurator is not limiting showed components to previously choose parameters.
e.g.
main product has 3 attributes – 1.base_model [PC_123] ; 2. CPU_type [INTEL]; 3. Max_wattage [200W]
now i want to add CPU to the configurator so i use same attributes for single CPU so it have [PC_123; INTEL; 200W].
At this moment the configrator is showing all CPU’s that has base_model attribute [PC_123] and limiting to [INTEL] and [200W] is not working at all. Please advice how to fix it ?
