Firefly Boards “Vary” is suddenly using Google Gemini instead of Firefly and I can’t change the model

I’m having an issue with Firefly Boards that just started today.

When I click Vary on an image, it automatically defaults to the Flux model, which costs 45 credits per variation. Yesterday, the same workflow was using the Firefly model as expected.

The problem is that I can’t find any way to switch the model back to Firefly. There doesn’t seem to be a model selector, so I’m stuck with Gemini.

I’ve tried refreshing the page, clearing cookies/cache, and starting a new board, but the behavior is the same.

Is anyone else seeing this? Is this a bug, a recent change, or is there a way to change the model back to Firefly for image variations?
