Do you like... NO !

Hello everyone, I have a problem with my ChatGPT since GPT5, ChatGPT end ALL his answers by "Do you like me to...", I tried to add instruction in the prompt personnalisation, but dont works, he still ask me:

- Never end your answers with a question.

- Don't end your answers with a question.

- Never end your answers with a proposition.

- Don't end your answers with a proposition.

- Don't ask me to explain anything else, to write anything, to create a graph or a table, nothing, the answer will always be NO.
