How are you using it? I think I've seen people on here who've had issues with odor didn't use the conditioner wash like a shampoo. You have to use it just like you would a shampoo and work a little bit harder. You need to really make sure that you're scrubbing your scalp very well to help break down any oil and residue on the scalp. Then you must rinse really well to make sure you remove all the conditioner and any dirt/oil/product residue that it's removing. After that you need to use a "rinse out conditioner' and you would use that like you would any conditioner. But your co wash needs to scrub your scalp really really well.
