How to remove last edited by when me as an admin edits other peoples posts?

[lUnknown]

What can i do? i don't have much knowledge so explain it to me step by step on how to remove this if possible, thank you!

Also is there a way so that it takes it away from posts that i have already edited? It would be really helpful.

You can change it in the usergroup permission settings for Admins.

yes even you set to "no" on usergroup and rebuild post cache still not working.
