Now this is even more interesting: if I write down the two records cited in the error message about duplicate values on CONTROL, then inactivate the key unique requiremnt, then open the file successfully, then mark one of the DEL (deleted), save the file, exit EpiData, then reactivate the key unique requirement, then try to reopen the file for data entry, I get the exact same error message: those same two records are cited as duplicated on CONTROL, even though one of them is now marked DEL.
