this doesn't work, or at least doesn't seem to. The challenge being: there is no "Imported Profiles" column, and anything that might be that column lacks any Sources or Last Search options
I am seeing this same issue.
Clicking add people simply produces a not-very-helpful popup that says CREATE SOURCE but offers no further way to interact.
The table was created directly from a search, as opposed to an integration, for example. It worked yesterday. Today, not so much
