ABC menu not displaying correctly

Hi —

The alphabetical menu isn’t displaying correctly. I’ve tried correcting it with no luck, so I deleted all plugin files, cleared the cache, and reinstalled the plugin. Here’s the main glossary page without any changes:

D and M aren’t lined up with the rest of the text, Y and Z break to the next line, and Z isn’t lined up with Y. How can I fix this?

Thanks,
Kristin
