QQ personalized signature, why always become a space update prompt? How to repair personalized signature? If you know, give me a hand thank you

The "system settings" of MS in QQ, but I'm not sure I haven't touched this thing for a long time. If it is not there, I will enter space. There seems to be a space setting, and there is an option whether QQ signature is related to space update. You can look for it. I saw it a long time ago, but I can't remember it now.
