Does your ChatGPT takes your Chats from the past and when you just review them, it’s randomly always going to the top?

Listen, I have a problem on my account you take my older chats and push them to the top like why is this I just literally pressing on them and they suddenly going to the top why I didn't even do this now they have a mind of it’s own like I’m literally only using it on my I’m not accidentally made it to go up I didn't even pin the chat, but what is happening? Like I delete my app and login again and still have the same results. Like I delete my app but instead of who is installing everything it still have that bag which made me angry so I did. Start this all over again.
