Can't change fill color on Type object and Paths in Illustrator

[goodboydesign]

I am running Mac OS X Mojave and the up-to-date Illustrator from Creative Cloud. For some reason lately I've been having trouble doing simple color changes with objects. Yesterday I had a layer that was a bunch of paths that were all the same color, and when I would select them all and change the fill (whether it be from the toolbar or the Color panel), it would show that the fill color changed in the Appearance panel, but the color didn't actually change at all. When I select all the paths and go to Edit Colors, It shows that both the old and new colors exist in the selection. When I use the magnifying glass icon in the Edit Colors panel to click on colors above and see where the colors exist on my artboard, it only shows the new color exists, despite actually being colored with the old color. Today I am having the same issue with a Type layer. It is black, and when I use the eyedropper or try any other method of changing the fill color, it remains black despite the Appearance panel reflecting the new color change. When I go to Edit Colors, once again, both colors show they exist. I don't understand why this keeps happening. The only way to get the new color is to change it in the Edit Colors panel manually. Right now, I can change the color of my other objects and it is just this Type layer that is giving me issues.

EDIT: I'm noticing now that I've created outlines for the Type, that if I ungroup all of the individual letters, I can change the fill of them individually. When I group the paths and select the group, I can't change the fill color of the selection.

Can you provide this sample .ai file including some very specific and clear instructions that may explain the issue you are talking about?

Also, which version of Illustrator are you using?

Paste items.
Now you can change colors. Or at least it worked for me.
