(Hint: you can use the Update Selected Log Entries command in the Log menu to fill in the CQ Zones in your log - but you will have to check them - many can't be determined by the prefix - in which case you will see a '*' where MacLoggerDX makes it's CQ Zone suggestions).
Make sure you back up your log before you use the Update Selected Log Entries command. It's only supposed to fill in lookup fields that have been left empty in your log - and it's supposed to do this with some degree of intelligence - for example not filling in the QSO Finished time or RSTR or RSTS fields etc.
