Own GPT Doesn´t learn and shows always the basic answers from the public GPT sources

Hey hey, why does my own created GPT not learn anymore?
For example i ask him :
How do I configure version control in OneDrive for Business via PowerShell?

He answered with Sharepoint Online management shell: Connect-SPOService
But thats wrong. We teached him the correct codes : connect-pnponline

He promised to remember in the next session and even told us, what to ask.
But a new prompt, or new session showes again the wrong standard answers, from chatgpt.

So it didnt remember.
It´s a complete new created GPT under My GPT´s
“Use conversation data in your GPT to improve our models” is marked

I hope its the right place und someone can help. Plan is “ChatGPT Plus”

Thank you :slight_smile:
