Additional Description field is gone

I migrated my WP site to GoDaddy’s managed WP. In doing so I upgraded WPEC from 3.8.12.1 to 3.8.14.4

The Additional Description field is gone from my Product pages now. Any ideas on what happened to that?

Here is the old site with the Additional Descriptions showing
