In Groups Drawings Revised

Dear all,

When I first start the models the fin plates in the beams are in same position,But now I revised the Fin plates Location in one beam.But still Shows the same position number without any notifications.In few Beams Means I can use Compare parts tool.

But in My case More beams are revised More same number position beams are not updated properly.

How to track this type of changes with the same position Number Structures.

Please give me your Suggestions for  me or Give me your valuable feedback  if any.
