If the net nam are the same, they will be connected together

Thanks for your reply. Is the net name different from the net flag name? When I click on GND in the Design Manager section of the schematic window, the GND wires are highlighted in the expected way - that is, not including the GND_POW wire. If the GND_POW wires are part of the GND net, then they should highlight red when I click on GND in the Design Manager, right? Nonetheless, there is no GND_POW listed in the list of nets. How can I ensure that net flag GND_POW has a net name of GND_POW? Thanks again.

please share your project with public, we will have a look

I think I have discovered a bug. Having pulled down the GND_POW symbols, automatically drawing a wire to them on the schematic and then closing and re-opening the project, it seems that the GND_POW net is created. If I click on the GND_POW net in Design Manager, the lengths of wire are highlighted. Please direct your attention to the GND_POW symbol connected to Q4 in the bottom right hand corner of the schematic. Drag the GND_POW symbol down to create a wire between it and Q4. Now click on GND_POW in the list of nets in Design Manager. The three wires which were already present when the file was opened will be highlighted but the wire which you just generated will not be highlighted, even though it should be part of the GND_POW net. It seems it is still part of the GND net until it is dragged to create a wire and the schematic is closed and re-opened. I think that this bug is the cause of my problem with routing in the PCB. The workaround is to create the wires, close and reopen the schematic but the underlying cause of the bug should probably be fixed.

Actually, closing and re-opening the schematic does not fix the nets but closing an re-opening the EasyEDA Client does.
