Create Connected System: HTTP

Hello,
I just started creating the SPX Launch Tracker app and when attempting to create the HTTP Connected System, I enter the name as instructed in the Step 2 of the Build a Low-Code App course, but it the error comes up saying "Name Already Exists". I am unsure when or how the name already exists even the app creation has just started. The SPX Connected System Image is not also coming up.
Any advice is appreciated
