Spring Tool Suite: Copying and renaming a Maven Web App

I have a HelloWorld Java app called FitnessTracker that I want to clone as another name, FDE3, leaving the original website in tact. I performed the following steps an attempt to do this. Please tell me where I went wrong and/or what else I need to do.

Change Context Root

Confirm Change Context Root

Still the original "FitnessTracker" name persists and I'm not sure how to get rid of it.

If I was able to successfully clone the FitnessTracker webapp as FDE3, I should be able to access the new site as

http://localhost:8080/FDE3

But I get an invalid resource error. Instead, the site is still accessible as

http://localhost:8080/FitnessTracker

..because of reminants of the old name.

What do I need to change within Spring Tool Suite to get the web app to use only the new name? To minimize chance of corruptying the project, I'd rather do it via the STS GUI over manual modification of any system file.

Sorry for being a noob.
