Despite the fact that it is indicated that no action is required, it still worries me.

Do you need to do something to get rid of these alerts or can you ignore it?

It is a debug-level message... just saying.

What ONTAP version are you running?

It is probably Bug 1322984 - EMS event notification after upgrade to ONTAP 9.7 or later

It can be safely ignored.
