Issue with the Kush UBK-2 Compressor

I just downloaded the demo for the UBK-2 Kush plugin after hearing great things about it. I am not sure if it is a bug, or if I am being really dumb, but I cannot work the compressor to not absolutely destroy any signal I put it onto

Here are the references for with the compressor and then without, level matched: (Obvious which is which)

On the one with the compressor, I turned off both saturation steps, turned the compression blend to 0, and adjusted the input so it is hitting around -10 on the VU meter. I am so confused why still it creates this ugly crunching sound as if something is broken?

Any help would be appreciated.
