The attached screen shot shows the results of a comparison between two models. The options “Show Unequal Objects” and “Show Unequal Properties” are selected in the Comparator. Why is the Comparator flagging items that are the same as being unequal? This behavior can be seen in the screen shot by examining the items expanded in the tree view. The details on the left hand and right hand sides seem to be equal, yet the Comparator has flagged them as being different.
