Catalogs represent a snapshot of your highlights at one time. If you create or delete highlights, make transcript edits, or rename speakers in a conversation you will need to "refetch" that data to see that update in a catalog.
How to refetch conversations and highlight data
While in a catalog on Insights, hover over the + icon. In the next menu, click Add Conversations. Click the search box to populate that field with any existing conversations. Check that this list is accurate and press Submit.
