Allow Admins & Moderators to mark a topic solved

Thanks for the swift responses! I don’t see an ‘Edit’ menu, and searching the Settings options for “Allow topic owner and staff to mark a reply as the solution” yields no results. I have this option, which is checked:

Menu - Admin - Settings - Plugins - Enable solved plugin, allow users to select solutions for topics

There are three other options on the Plugins settings page (also when I search settings for ‘solved’). They are depicted below.

Am I missing something?
