Lopsided playback

I’m having an issue with my playback a melody line of straight eighth notes. The score reads eighth notes. The piano role has the notes lined up nice and pretty like eighth notes. When I play it back it sounds more like dotted triplet rhythm with the first note a taste longer then the second. I’ve produced a number of other pieces where the melody was built on the eighth notes that worked. For some reason this piece is somewhat loop sided. Any ideas what could be causing this anomaly.

Hi,

Is there any MIDI Insert or MIDI Modifier used on the track?
