I'm running into some major issues when working in the Lumetri Color panel in Premiere 22.1.1. I have some test footage that I've been working with and when trying to use the eyedrop tool on the different hue saturation curves it isn't able to select the color that I select. Instead, it places a point in the middle of the curve.
I also noticed the auto button is not working in the basic corrections panel.
Upon further investigation it appears there is an issue with the main RGB curve in the Lumetri Color panel. After applying a basic S-curve I ran into issues when trying to use the hue saturation curve eyedropper. It always grabs red in the middle. However, when I turn off the basic RGB curve I can then use the secondary eyedropper to select any color I want.
I am having the same problem, when I turn off the basic RGB curve it just chooses a different, incorrect colour range. This seems to have been an issue for around two years now from other comments I have seen. I am surprised Adobe hasn't done anything about it yet, it's not a small issue when colour correcting.
