Can't drag sliders in Color Wheels & Match.

In the Lumetri Color panel there is the "Color Wheels & Match" window. Usually you can click and drag the crosshairs from the middle of these wheels to anywhere inside the wheel. Usually you can also click and drag the sliders to the left of the wheels. 

For some reason I can only click inside the wheel to change the paramaters/values and I cannot change the sliders to the left of the wheels at all (can't click and drag the slide and can't click above or below the slider to move it). 

I'm assuming there's some random setting or check box I've accidently turned on, but can't find anything about this problem anywhere. 

This was a problem yesterday before I updated to 25, and its still a problem today after updating to 25. 

How do I fix this?
