This is an annoying and regularly arising nuisance. It really is time Apple did something about it.
I've mislaid the thread link but Dah*veed wrote recently to offer the following solution. Hope he won't mind me repeating it.
'You could try reindexing your HDD. The MAS uses the Spotlight indexing in determining what apps need updating. Go to Systems Preferences / Spotlight/ Privacy; add your Hdd to the list then remove it from the list. Spotlight will then reindex your HDD.'

All too often this doesn't solve the problem. I used to think the same but too often the alert remained because people had saved, backed up or copied the original download into other parts of their system. Then it's necessary to use spotlight and /or use EasyFind to dig out all the files.
Damned nuisance. They really ought to sort it out; enough threads are being started because of it.
