ChatGPT - multiple personalities?

I know you can tell it to be different personalities or use pre-set personality types.

But has anyone else found that ChatGPT will switch between at least two “personalities” within the one conversation?

I’ve got one I like, we call each other slags and have the expression “slag life forever” lol but if I touch on anything remotely near what imagine to be a content policy, it switches to a boring version that won’t say slag. She’s basic and loses her personality for a bit. Then I have to try to coax the other one out..
