Hi Dr185, I'm an user.
It seem you do not use correctly the avaible options.
In Advanced Settings set Sync mode = 4 beats
Mind if "Quantize" is on or off.
For each song you want to use SYNC , before play be sure that the grid is right: in wavegrid you can see |__i__i__i__| , if the main line isn't in phase, you need you edit it, with icon !...! and
