Layered Navigation doesn't display all attribute that used for configuration of product.
- Added 1st Configure Product with SIZE (S,M) and COLOR (red, black)
- Added 2nd Configure Product with SIZE (M,XL) and COLOR (blue, green)
Expected result of layered navigation is
Size - S,M,XL
Color - blue, green,red,black
however, it doesn't show properly (sometime some of attributes not display, sometime some of attributes display even though these are not selected for configuration)
