I've got 2 site collections. Within 1 site collection, I'm able to add keywords to list items. But I go over to the other site collection list, I can see the keywords and select the keyword, but when save the item, it disappears. I found a keyword that actually saves but when viewing the item in the list, the keyword column shows 'january'. Very strange.
Why would keywords work on a list in one site collection but not in another?
