net port from schematic doesn't correspond in PCB

Hey guys, new user here! I have a small awkward problem, for some reason some of the net ports from the schematic don't correspond in the PCB. I give you an example. I had a net port named IO12 who linked GPIO12 with the LED1. When I generate the PCB, the LED appears to be linked with another GPIO. Same happens with the  R7 - EN wire. I tried to link them directly without net port but it didn't seem to change anything. What I'm missing here ? Thank you in advance! link of the project: [https://easyeda\.com/mariusmym/esp12f\_relay\_i2c\_sensor](https://easyeda.com/mariusmym/esp12f_relay_i2c_sensor)

The problem is that you have not checked the pin to pad mapping of the Schematic Symbol to the PCB Footprint. I have no idea where the schematic symbol and the PCB footprint that is assigned to it comes from but the PCB Footprint pad assignment is total rubbish and bears no resemblance to the normal pin ordering around similar packages. The references to LCSC part and the stock number stock numbers are also junk. I suggest you either: 1. delete the Schematic Symbol and find a correct one to which is assigned the correct PCB Footprint or; 2. if you are sure that the symbol is correct to the datasheet, then find, edit or create from scratch a PCB Footprint that is correct to the datasheet and then assign your new PCB Footprint to the Package attribute of the Schematic Symbol. For guidance on this please read the Tutorial and for more detail, please read (2.3) in (2) in: [https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a](https://easyeda.com/forum/topic/How-to-ask-for-help-and-get-an-answer-71b17a40d15442349eaecbfae083e46a) * I have reported this PCB Footprint error using the Report Error button for the symbol from within your schematic.

@andyfierman thank you very much for your support! Holy #%$*, i completely forgot to check out the footprint assignment ( I made one or two libraries and I know that footprint assignment is essential). I used that library symbol before, for my first order at jlcpcb and  the dimensions are ok. I still want to use it because of those holes that allow me to place pogo pins for programming. The main difference is that in the other project I used wires to link all  components. Thank you one again! I'll try to correct this symbol.

@mariusmym, Without seeing a datasheet for this module I can't be sure but I don't think it is the pin number and ordering on the Schematic Symbol that is wrong. I think it is the pad assignments on the PCB Footprint that are wrong. So you need to edit the PCB Footprint, not the Schematic Symbol.
