Please note that `HDR-12X1/2.0` is a System Component PCB footprint not a schematic symbol. If you open `HDR-12X1/2.0` for editing then it will open in the PCB Footprint editor: ![enter image description here][1] I cannot find a schematic symbol called `HDR-12X1/2.0` anywhere in your EasyEDA home page or a SHIFT+F search of the EasyEDA libraries. Without sight of your project or at least the schematic symbol and PCB footprint you are referring to it is difficult to diagnose what the problem may be. [1]: /editor/20170305/58bbed64526bc.png
