Figured it out. For some reason, several of the objects in my template, under the Listing and Labeling section were looking for a Linked Property (Individually even though the option wasn't turned on) called DRAWING, which didn't exist in my libraries. Turning on the "Individually" option, selecting a different Property, and then turning the option off again.
