Double categories after installing CCGV

[lroschi 0]

I installed CCGV (latest version here) and although the things I've tested have all worked fine, I have this crazy second column of categories along the left side of the checkout page. Everything looks fine until I click on Checkout, then all the screens during checkout show another category column. The contribution itself appears to work fine on what I've tested so far. Can anyone help with this, or lead me to the answer? Thanks for any help you can give!
