This Scope Is Already Taken by Another Application' Error in ServiceNow

[RetinaKumar]

I have started learning ServiceNow and I am trying to create an app in my PDI. I am following the steps as mentioned below.

1. Go to navigator and go to My Company Applications. 

2. Click on Create, it then opens up another window to open ServiceNow Studio where I need to provide Name and Description and select if it is a scoped app or gobal.

3. After adding the details, click on Continue and in the next window keep the roles as it is and click on Continue again. This is when I get the error - This Scope Is Already Taken by Another Application' Error in ServiceNow.

This happens no matter what name I use and I tried with many - such as My Unique Devices, or my name devices or Device Management or Test Application.. I even reset my PDI 2 times to see if that helps.

I also checked in sys_scope.list but I could not find any scope with similar names that I used. I am not sure what is happening. I am stuck and cannot continue. Please help. I have added screen-print to show you the error. If anyone needs any further information to help me , please do not hesitate. Thank you all.

I'm continuously changing the application ID but I'm getting the same error - This application ID already exists. Try entering a different one.

Hi thank you for your reply , however as already mentioned in my question, I have checked sys_scope.list and could not find any matching scope/app there. Moreover I have tried many combination including yyyymmmmdddd my initials and then app name and that also resulted in the exact same error. I can share the screenprint if needed.
