Studio One & Scaler 3 Question

I have 4 measures of Scaler 3 using internal sounds (Lofi) and a scaler midi riff open in Studio One. I then duplicated the midi riff to extend to 8 measures. When playing back, the first 4 measures have sound (Lofi) but the next 4 measures are not playing the main track back in scaler 3 (no sound). I have “Daw sync” enabled and the song is still playing but the scaler main track isn’t playing. Is this by design?
Thanks
