"Advanced Options" not showing all tables for main site

Hi there,

I'm trying to set up a new Blog Template and for some reason there are certain tables missing under "Advanced Options." Each site on my network has a few custom tables added by plugins, and these tables show up for all of the sites on the network except for the main/parent site. Any idea why that might be? I'm trying to use the main site as the template and I need to include these tables as part of the template.

Thanks in advance,
Sean
