Weird errors after postfix restart

[Deam]

Hello, I have a little concern that something went wrong with postfix after the update. Below I upload the warnings that appear when restarting the service, what should I do in this situation? The files are different. should I replace them with files from second path?
Never had this problem before hence my question. Greetings and I would like to ask for some guidance.
