I had entered a picture to be analyzed by GPT-4o. It's run well. I make a branch from certain chat point below. Now, the problem is when I delete the branch it also deletes original one. It deletes the pictures and some chat from original. This is crazy.

I think for branch, you'd better make a copy for the branch. But if it's by design, I think it's really unintuitive. Logically, when we deletes the "copy" or branch, the original one shouldn't diminished.
