Can't change specific colors in the theme

If I choose a base color or a base highlight color, uiXpress automatically generates a color scale from 0 to 950. But after selecting a base color, I cannot manually change any of the colors in the scale. This is somewhat related to the other bug I reported, in which I would try to change the color for “500” in order to fix that other bug.

If I click the color, the color selector shows up but the color code does not change. If I type in the hex code, it won’t save.

If I choose a new base color then it recreates the scale, but I would need to change a specific color in the scale - in this case, the “500” color.
