Uncheck Minimize Rests in the Notation Options dialog and you'll see rests shown in the bar containing D7 D7Sus. In general, the notation may or may not always look 100% identical to what the XML file specifies, because the notes are actually what is imported based on the time locations, duration, and attack/release, and there are things BBW that doesn't support like multiple independent systems (multiple independent groupings of notes) within an individual staff line. But unchecking Minimize Rests does result in rests in that specific example where the rests were not being shown.
