Followed the video "Gradients (Part 3, Color Ramps & Dissolve)" to make a burning edge dissolve, but my base texture is tinted with an emissive gray overlay

My results for this are different than Joachim's even though I followed the instructions exactly. In the comments of the video I noticed another user had the same issue.

Here is a screen shot of my issue, as you can see the display texture has a gray overlay when the slider is at 0, should look like the base texture 2d.
