Those are expected, local multicast is used by modern operating systems for automatic network and service discovery.

Leaving these logs in place would not be a problem.

Additionally there are a couple of different ways you can either block this traffic before it is logged or turn off logging for this traffic.  There have been a couple of fairly recent threads covering this issue.
