Hello Rose, 

Using Google App Engine, an application ID is actually identical to the project’s ID. In any project, and like you did, and in addition to Google App Engine, you can always use other products (like Google Compute Engine). However, and while they are all in the same project they are in fact separate resources. For further information you may check these documents about application ID, and  Project ID.

I suspect that you could be confusing both resources despite their differences due to your old application on GAE is still active. Thus, you may disable it per this guide. I hope this helps.
