Is this remix UI new?

What's the purpose of this? I have simply been using the remix function to work with the prompts and settings of the images I previously uploaded. I can't find a button to turn it off, and sometimes images that are completely unrelated to the remix appear. Even when I change the prompt, it stays the same. Does this affect the images? I don't understand why this unnecessary and annoying feature was added.
