Engine sync to SSD

I am having issue that the playlist do not sync across correctly all files are in the collection but they are not going across to the ssd a plus list of 500 comes across as 2 tracks. how ever its all correct on the MacBook the full playlist is visible. its very odd Mac and Monterey

I should also add that the lock Icon no longer funtions although you can lock a track. it would appear that Engine may be corrupted any advice on how to address would be helpful
