Edit app description without updating app?

I have a pretty basic question, and I couldn't find anything about it in the developer logs... I just submitted an app to the app store and it got approved this morning (yay!), but I noticed that there are two website links listed below the description, and I only want one. When I filled out the description, I put the same URL for both Application Website and Support Website, because I didn't know both would show up... Here's the link to my app.

I want to get rid of "John Schlemmer website" and just keep "MySuiteStuff website," so I removed "application website" and kept "support website" in the app information on iTunes Connect and saved the changes, but it's still showing both in the app store. How do I update this simple information change? Do I have to submit an entirely new update? I'd really appreciate anybody's help on this.. thank you!!
