Color Picker Changing Entire Stroke From Gradient to Color

When I use the Color Picker inside of the Gradient window, it works fine and normal on shapes, but if I try to use the Color Picker when adjusting the gradient of a stroke on a shape, it switches my gradient to a solid color. I'll attach a video to show what's happening.

In the video, the first thing I do is select the shape with the stroke on it. Then I make sure that I'm adjusting the stroke gradient and not the shape gradient. After that, I move over to the Gradient window. I click on the Color Picker and then click on a color from my library. You will notice that the stroke is now a solid color instead of a gradient.

I do two things to test if this is an issue with selecting colors from my library. The first thing I do in my screen recording is use the Color Picker on a color located inside my Illustrator canvas. You can see that the Color Picker worked. The second thing I do to test if it's a library issue is to use the Color Picker on the shape rather than the shape's stroke. This works. I'm able to use the Color Picker to select a color from my library without it changing my shape to a solid color. 

Is anyone else able to replicate this issue or am I the only one? Or am I just flat-out missing something?
