"After the Deadline" spellchecker numerous buttons

We're getting a weird thing in TinyMCE. We get many buttons for the spellchecker after we indicate in Site Setup that we want to use it.

Anyone have an idea what could cause that? It works OK. It's just odd.

I appear to have figured this one out and fixed it. There is a setting for the toolbar in Site Setup that somehow got numerous instances of the icon added to it.

I am new to Plone and still figuring out basic stuff.
