No one can see my information in private

No one can see my information while chatting privately, but I can receive secret messages from others. You can see any other channel information! It has nothing to do with the plugin (already tested)! May I ask what the problem is! My role: Roibert My account: sy19891120 Request help! thank you!

I chat privately with anyone, they won’t be able to see my information! But I can see them chatting about my content privately.
