If I select for example GPT4 write a message, and then edit my message, so it creates a new branch, then it will use Claude 3.5, all following messages after this will then be again using GPT4.
It also seems like it is still "aware" of the previous reply it gave, which should not happen.
Only use GPT4, and the model shouldn't be aware of its first reply to my old message which I edited.
