Record date is a generic date. The main date is the ex-date (ex-dividend date). All other dates depend on this one. Anybody in possession of the stock the previous day, gets the divi.
FINRA declared the ex-date as 8/19 according to the rules. So, everybody who had shares in 8/18 get the divi. The new record date would be 8/20. The date is just the time needed to know who was in in 8/18.
