This article will outline the effects of updating (editing or deleting) the list of Classifications in your Words and Phrases Dictionary.
If you update an existing Classification (under the Classifications page) by editing its name, the list of Words and Phrases will also update the name of this Classification as per the change you have made.
This type of change will not affect your setup for existing alerts however, and you will have to update those manually or create new Alerts if you want these changes to be included.
Note: If a Classification is deleted, any words or phrases listed in your Words and Phrases Dictionary that used to have this classification will now have their Classification set to 'Unclassified'.
You can go ahead and edit the Classification for these words and phrases to something else when clicking back into your Words and Phrases Dictionary list.
