Old column names exists even after renamed columns

Editor assessment

The subject captures the bug in plain terms: old column names continued to exist after columns were renamed. Although grammatically rough, it conveys the symptom and affected area without the diff. The fix type matches. No scope is present; the widget context is implicit in the wording. There is no body, which is acceptable for a small defect fix whose subject already states the observable problem. No footers are needed. Hygiene issues are limited to the non-imperative, subject-verb-agreement-broken phrasing, which slightly dulls an otherwise direct and comprehensible message.
