Greetings Scott, A product's display label will disappear if its data isn't available for a given time step but other data included in the display still exists. Perhaps this is what you are seeing? I'll ask around on Monday to see if anyone has a grasp on how often this is an issue, although a brief look through past IDV tickets and replies indicates it's a known problem (unfortunately, one with no known solution); one user even reported an approximate 1 and 10 dropout rate.
