You can remove the unwanted tag by going to a profile manually and clicking on the "X" next to the tag
If you are not sure what tags have you used, you can check them by going to "Search by Tag" on the Dux-Soup menu.
Here, enter the tag you want to search for or see which tags you have used
When you enter a specific tag, it will bring up the list of profiles. Then, you need to go to each profile manually and remove the tag from that profile.
