Product Detail View – Tabs Disappeared

My product tabs disappeared. I have done some research and think it might have to do with some attributes and/or product information upload.

I am missing the Additional Information Tab and the Tags Tab. I entered some tags for a product and I can see the spot where they are listed on the product detail page, but they aren’t in a tab.

I have removed some of the attributes that were part of the sample data from the install. I have also added a MSRP attribute, and a test attribute, I have made these visible on the front end but they just show up below the details, not in tabs.

How do I get the tabs back?

I have attached a screen print.

Thanks
Janice
