This error occurs while importing slogans, if Q++Studio notices that a Month-Day pair has been repeated.

 

Common causes are

 

•Importing a text file with over 366 lines.

•Importing a text file into a non-empty slogans set, where the total number of entries is more than 366.

•Confusion about how the Month-Day slogans set type functions.

 

For more details, see importing month and day slogans from Excel.
