When opening a schematic design made with older DxDesigner ( <= PADS flow 2007.2) it gets converted to the new format.
The conversion creates an extra sheet after some of the schematic pages.
The extra sheet contains "Generic_Pin" symbols and a short net connected to it.
The pins have NET_NAME attribute with the same value as the net's name.
The nets are actual power source nets or NC net etc which exist in the schematic elsewhere.
Why are those pages generated? How to prevent it? Is it safe to delete them once they are generated?
