I use the Image Trace function on Adobe Illustrator all the time, and usually it works fine, but I just encountered an annoying issue I'm unable to solve.
What I usually do when tracing images is I place the photo/image on the Artboard and bring up the Image Trace window to tweak the parameters until I'm satisfied with the result and then proceed to trace and expand the image. After that I Select (V) the resulting image and change it's colour. Works every time. Except now.
For reasons unknown, after starting to work on a project today, I noticed that with each traced and expanded image, the fill of the selection has a question mark on it, indicating that two or more objects have different fills in them. If I change the colour of the fill, the entire selection goes gray. I have to use Direct Selection (A) + Shift to select each part of the image separately in order to change the colour which is difficult and slow and doesn't even work properly every time. And even then, upon changing colour it still turns gray, and I have to manually change the Color Palette back to CMYK each time.
It's driving me insane. I haven't seen this problem before and I've tried to create a new project and restart Illustrator but nothing works.
