If the same person exists as two separate candidate records, merging combines them into one.
Steps: open the three-dot menu on either profile → Merge Profiles → select the other profile as source or target → confirm.
Things to know:
You need edit scope on both the source and the target profile — the system validates this on both records before executing the merge.
Merging is typically irreversible, so double-check which record you're keeping as the primary before confirming.
