I reopened Firefly the day after and the renders are all a different style

I mean my final exports are different from the first generated, if I go to my favourite that I saved, they have changed style and are different, imagine now. it's very strange. The are other imagine now.

You can use an image as a Style reference.

Are the renders different when you new prompts is a new Firefly page or when yoy try generate new images in a page with previous image generations? Have you included any new text that describes the syle?
