Show Attributes checkbox not doing anything

Clicking “Show Attributes” isn’t showing any attributes. It’s possible I don’t understand this functionality. I want to add notes below the words that designate Plural/Singluar and Formal/Informal. How can I do that?

It looks like you need to add a column for your attributes.

How many levels has your course got? If it’s only one, first add a second level. This will give you access to the databases and advanced features. When you have added a column for your attributes, you can customize it by clicking on the grey pencil in the column header.

Good luck! Come back if you need any help.
