How do I remove/delete an offline item

Recently I've noticed in the Windows app a cloud with a line through it (which to most people would mean your off-line but I'm not). Why would it show this way when I'm online? Because when I am online I'm hoping I don't have to do anything to keep all of the information synchronized. Shouldn't it automatically do that? Possibly related to this icon is the fact that for some reason it shows that I have one off-line item. Don't know what this means either.
