So after upgrading to 12.0.1 I noticed that if you expand one of the All Nodes device types I have about 70% of the nodes are listed twice. Not every node just most of them. Knowing that duplicates aren't encouraged, I click on Manage Nodes and all the nodes are listed only once. I only see the duplicate nodes from the Home page All Nodes section.
Any ideas why this is happening?
Any ideas as how to fix it?
Thanks for the help.
