How can I handle this?

I also had the same, i followed these steps it's working fine now.
- Click on Remove this app from Enter THE APP DETAILS section.
- Change the pacakge name of the application that you are trying to add.
- Now replace the newly created package name in ENTER THE APP DETAILS section.
- Now just give the SHA1 finger print key
- Done.

Maybe you have a duplicate project which you deleted long ago, but when you go to the page where you can set your project API and click on "manage all project", the deleted project actually is still there and you'll have to delete it there.
Check these questions:
