View does not refresh on undo

Using demo network number 1, select pump 9 and edit it. Select the start node field and then click in the map on junction 21 so that it becomes the start node. Press OK to apply the change. The auto-analyse immediately shows 210 warnings because of the change. Select Edit > Undo. Auto-analyse shows that there are now no warnings, but the map still shows the pump connected to junction 21. Refreshing the map view updates the map correctly. Running version 1.1.1
