Maybe the cables are crossed somewhere....

Besides having the correct signal level into MAP65 you must also
have the correct time. Maybe WSJT searches in a slightly wider range
of time offsets than MAP65. Look for the time of those transmissions
that decode and make sure they fall well within the search window.
I do not have the details, but they should be available somewhere.
Something like -2 < dt < 5
