I'm John from the UK. Just got a Nome II to import my samplers into Logic.
Only had a play for half an hour and have come up against something strange. When syncing my SP1200 it starts exactly a bar late, but if in cycle in Logic, when it goes back to start of the cycle it resets to the correct first beat.
U-SYNC in Logic is a bit "sensitive", are you sure the U-SYNC track is not record-enabled or selected?
And what value do you have on the U-SYNC slider?
