Reset Button Not Working in Develop

I pasted an edit to my picture and tried to reset the white balance by double clicking the sliders. It seemed like it worked (I could see the white balance change), but when I clicked the before and after view I could see the white balance didnt match the original. I thought maybe it was another setting that was changing it so I tried clicking the Reset button. While that seemed to work by resetting all the sliders back to zero, the white balance still looks different in the before and after view. Does anybody know what could be going on?
