If you have a view with a large number of tags. You can use this script to check if you have duplicate tags for the same elements.
You can run this script from Dynamo player and choose which tags you want to check. After the script finishes with the check in case that you have duplicate tags with the same value for the same element those tags will be colored in red color.
When you resolve the situation with duplicate tags (change the tag or delete duplicates) you can run the script one more time and for all the tags where we do not have duplicates anymore for those tags, the script will reset the color.
Please make sure that before you start using this script that you back up your existing project model.
