Kiinde system

So I bought the kiinde system for ease when I return to work full time. I wanted to try it to see if my baby would take to the bottle/nipple and was okay with it. I noticed a lot of noise when she was drinking so I don't feel like her latch isn't good on this nipple. She's taken other bottles and have had no issues (expressed milk with enfamil disposible nipples and an avent bottle that was free from target). I just don't know what to do with her squeeky latch with the kiinde bottle/nipple. Should I return it or is there another solution? Anyone use this product and had the same issue?
