The midi file might have an effect but, in this case, both features are working on exactly the same midi file. The Open Special does not allow for any parameter input from the user so you get what you are given. The subsequent dropping of the midi file onto BB does ask for offset parameters. The second feature with an offset of 0 should be provide the same alignment as the first. Fortunately it's easy to spot in the Tracks view and correct using further drops with an offset +/- dependending on the direction of misalignment. This is definitley a BB issue.
