Hmmm ... I highlight a verb and it is coded for AF noun categories -- all of them?
They're all milestones on that article (so that clicking on a reference in the Information Panel etc. can navigate you to this glossary). The context menu always shows all milestones for the current article. We didn't build in a feature to collapse multiple ones because I guess we didn't expect there to be 20+ milestones on a single article.
The "fix" might just be to delete them all from the resource.
Good to know ... I thought the Context Menu was more targeted but I can understand the choice in implementation.
