Search API ItemType missing Node I am using Search API and search views to add facet blocks into my views page. It works perfect on my test site with only search/facet/views related modules. 

But on my working site, when I add Search Index, the ItemType is missing "Node" selection, instead, it is showing "Content". I have updated all modules, but can't figure out why "Node" option is missing. 

Anyone has ideas on this?
You do not need the "Node" Item type. Using the "Content" is going to index all your nodes.
