In your Cumulation ID tab, make sure your /7xx WTs are listed under both RT and CRT cumulators if they are part of cumulations (or Totals).
In your Change Window tab, for the appropriate Change Group, make sure that the /7xx WTs are listed for both RT and CRT tables, each with it's appropriate Line Type.
