The possible actions when a candidate is selected in the "Candidates by Owner" (second screenshot) is different than the one from "Candidates by Job" (first screenshot).
Since the dashboard looks exactly the same, it's weird that we don't have the option like "Update Hiring Stage" in this "by Owner" Dashboard.
This becomes a bit annoying when you just want to add a Remark on the current Hiring Stage but need to go to the Candidate to do that
