This message occurs while converting a Slogans Set of type Specific Dates to one of type Month-Day, if the Slogans Set contains 2 or more specific dates that correspond to the same Month-Day pair (for example, January 12, 2020 and January 12, 2021).

If this happens, we suggest that you export the current Slogans Set to Excel, remove the dates that will lead to duplicates, and then re-import it from Excel, before attempting the conversion again.
