All of my seasons had disappeared for all my shows with the "upgrade" to 10.11.0. I had to reinstall thetvdb plugin. Then refresh the metadata (replacing images) brought the seasons back. But then they disappeared again some time earlier today. That trick didn't work to bring them back. Went up to 10.11.1 to see if that would resolve it. Still can't get the seasons to come back. Have restarted the server and refreshed the metadata a few times now.
