bug: AI model screen doesn't always stage green check mark if AI model is already selected

Encountered a bug during test to resolve PR #22 

If I already had a AI model in memory and then had to go back to the API key or AI model screen then move forward, the checkmark will change for the AI model.  We already know a selection is made.  We need to ensure it stays with a green color and a check mark like the others when the AI model choice already has been made
