Fixing Comment Box Proofing in word files in a document originally created in another language

Ran into a problem today. The collaborators for the project we are working on are foreign so the document they sent me is defaulted to their native language. The challenge is you can simply change the proofing language Review > Language > Set Proofing Language ...  however I noticed when I added comments they still retained the original language. The quick fix for this is:

1. Show the "Styles" by clicking the Expand Box in the Styles section of the [Home] Tag ribbon
2. Click [Options]
3. Change "Selected Styles to Show:" to all styles 
4. In the style window right click on the Comments Text > Modify 
5. [Format] > Language > Select English!
