Filtering

Hi,
after we installed Bulky I could filter perfectly by all kind of filters… It was like we hoped to find a plugin to do so finaly. My friend on a other device wasnt able to filter… A few days later I have shown him how to do and he told me that he made the the same process… But we have been happy, that it´s working.
Two days after I used BULKY again and from there on, I spent hours to find out whats wrong…. I can no more filter the products as I did befor. Since days now.
Why!?!?!??!????
Whats woring? I do not understand why the hell it was working in the beginning and now it isn`t.
I want to filter all prducts whit for example 100x50cm whit for example Alu Dibond Direktdruck and without a Frame (ohne Rahmen)
There should come just thous Products and there Variations and not every different Material and also with frame includet…..

ceck out the pictures below.

I hope you can solve the problem! Thank you in advance!

We need to be filtered just those Products and Variations that we insert:
Fot example:
Categories: Open-Edition but from those Categories just the Variations with:
Size: 100x50cm
Material: Alu-Dibond – UV Direktdruck
Frame: ohne Rahmen
