US profile assignment change. US Chan ID: 8; Previous Profile: 11

I am getting multiple instances of the above message (25 in the past hour) in my Netgear CM1000 logs.  The profile number changes between 3 profiles.  This has been happening for a few weeks now.  These are listed as "notices" so I don't think they are serious but wanted to check to see if I should be concerned.  Thanks!!
