Result { "results": [ { "ticker": "THC", "name": "Tenet Healthcare Corporation New", "market": "stocks", "locale": "us", "primary_exchange": "XNYS", "type": "CS", "active": true, "currency_name": "usd", "cik": "0000034956", "composite_figi": "BBG000CPHYL4", "share_class_figi": "BBG001S70FY0", "last_updated_utc": "2024-07-24T00:00:00Z" }, { "ticker": "THC", "name": "Tenet Healthcare Corporation New", "market": "stocks", "locale": "us", "primary_exchange": "XNYS", "type": "CS", "active": true, "currency_name": "usd", "cik": "0000070318", "composite_figi": "BBG000CPHYL4", "share_class_figi": "BBG001S70FY0", "last_updated_utc": "2024-08-02T00:00:00Z" } ], "status": "OK", "request_id": "d2e9593cfd4bdfb19f3ac472166ce9e9", "count": 2 }

Expected Result The record with CIK 34956 is wrong (the actual ticker is TENX)

Additional context Dups started on 2024.07.27, its possible other tickers are affected too.
