After the upgrade server and agents for Windows-based systems to version 1.7(1.7.1), stop getting the message logs(EVENT LOGS)

Here I noticed, if you leave the agent of previous versions (1.6), then the message will come, but the field eventid (ID events) because of which I am so playfully updated, empty
A piece of log Agent version 1.7 (8079)

And the log agent version 1.6, which shows that the agent handles the message.
