Swift iOS - subscription receipts for each apple ID?

The application that I am working using the subscription model and validated the receipt get the information it needs to give (or not) the user access to full functionality. I was doing all my initial development using one testing sandbox account.

Now, when I was starting to take the testing from the top again using a fresh sandbox user, I signed out of the initial Apple ID I was working with, and deleted the application from Devices. When I ran the app again and looking at my console debug I was surprised to find that it found the same receipt that was being used by the first Apple ID and started validating it!

What am I missing here? Why is the same receipt being found while I have sign on using a new sandbox test account?

Thanks
