In SmartStruxure version 1.5, when editing a graphic or program while having the bindings view open adding, deleting or renaming binds, the bindings view doesn't update with the changes when the change is saved. Manually refreshing the view doesn't update the view either. You need to close the view and open it again.
SmartStruxure version 1.5
This is a bug already reported to Product Support
For the time being there's no fix for this. You need to close and reopen the bindings view after having made changes to the graphic or program.
