[Risolto] I cannot transfer credits back, and Ive deleted the key?

Background of the issue:
I was trying to transfer credits back, but I have deleted the key for trag.internetcoding.solutions. The site no longer exists, and I have removed the key.

Symptoms:
In my credits section in the user dashboard, I see a blank space where the name of the website and the credits should appear. I cannot transfer them back for some reason.

Questions:
How can I transfer credits back after deleting the key?
Why is there a blank space in the credits section where the website name should appear?
