All my actions have turned into hyperlinks

As I was working this morning, something I did turned all of my actions into hyperlinks. Any idea what I might have done, or more importantly, how I can make it go away?


All actions are in underlined blue text.
Clicking on any action opens another action. In all cases, it is the same action that opens.
“Undo” did not work.

Update: Actually, all links appear to be self-links. They open the same action in a new window.

And, now, it’s fixed. I went to the preferences and reset styles.
