Bug report: Removing colour tag
Finder has a bug when I am trying to delete a colour tag.
I had inserted a green tag in a file and today I wanted to remove it. However, as you can see in the screenshot, the file remains in the "green tag" folder, even though it no longer has the green tag. I have tried to add again the green tag and then remove it, with no success. I tried to add another (blue) colour tag and then remove it, but what I achieved is that this file is now in both the "green tag" and the "blue tag" folder.
I am using macOS Sierra 10.12.3
This bug also existed in the older versions of macOS Sierra (for el capitan I don't know).
