Video changing colours to bright pink

I generated a video from and image with Firefly and the video after 2 secondo changes colours to a very bright pink. Even tho prompt instructed not to edit colours. I lost 1000 credits to this

Image to video

Firefly Video generation tool . 9:16 aspect ration, 6 seconds long. 24fps

The video start with roughly 1 second of good generation but then suddenly it just turns a very bright magenta color.

Prompt specifically asked not to edit color
