Alphabetical order

The links to other words that appear above and below the glossary entry appear to be taking me not in alphabetical order, but instead, back to the previous entry I made and then forward to the next entry I made in time. So, say I entered a word that started with Z, then one that started with L then one that started with C in a glossary that is already full of words. If I click on the L entry, it will show a link on the left to the Z entry and on the right to the C entry. I would think this is supposed to be in alphabetical order and the the entry one prior in alphabetical order for L should show on the left and the one after in alphabetical order for L should show on the right? Or can I turn this off altogether? I don’t have the pro version.
