Couldn't find the initialized API data in the Repeating Group's Fields

I’m using the API Connector to retrieve data, and I use the data from api connector in many places. However, I have created a new one, but I can’t find the ‘Type of Content’ and ‘Source Data’ fields. I’ve tried reloading and clearing the cache, but it hasn’t helped. check the screenshots. What I done wrong here.

Searching the api by prefix

Pasting full API name but it showing invalid value.
