Some Responses auto-deleted when editing the latest message

has anyone experienced this before? so I’ve been using chatgpt 4o to do a long conversation about a topic, but then i typo and made the response a thing i didn’t like, so i edited it, but it ended up deleting most of the responses from before, even though the edited message was the latest message I’ve sent.

and also typing in chatgpt is weird and bugged too, so i had to copy paste from another app.
