Like I said, you can't just manually edit dictionary values. It's only done with the code. Right-click the dictionary in the list of objects and select "Find all references" to find all events where it can be populated.
It's possible that the game loads the values from a file. Check the Files folder in the project.
Is there a way that I can download the information in Debug mode?
It's not possible. But you can add an event that exports the dictionary, for example:
Keyboard On "D" key pressed : Dictionary Download
