[BUG] AI Studio -System Prompt is not loaded when model is updated

Sometimes, when I load an old prompt file, the System Prompt is missing.

I believe this happens when the original model is unavailable, and AI Studio automatically selects a new one. Even though the system prompt data is still in the JSON, it doesn’t load in the UI.

The message displayed is:
“Model in saved prompt is no longer available, so a new model was selected.”
