Component Schedules only schedule composites and complex profiled elements ... those elements that have 'skins' (the components).
You would use an Element Schedule to schedule your mesh quantities. It sounds like you did not set up your criteria correctly. Should be 'mesh OR slab OR beam' etc to get all of the footing elements... enclosed in parentheses... and then choose the concrete material.
Repeating Laszlo's question - please post a screenshot of your schedule criteria. I'm relatively certain that the problem is your choice of settings there.
