You need to give more information to clarify what you mean by "Once in my PCB, it looks like a VCC." This could simply be because  somewhere in your schematic, you have accidentally connected the net that connects to pin 37 of the chip, to VCC. Then, when you converted the schematic to PCB you noticed that the track and pad net names have appeared as VCC.

Sorry, english is not my native language. What i mean is that, once creating/updating my PCB, the same pin is changed to a +3.3V, which also exists in my schema, but isn't crossing that wire at all. Since it "thinks" it's a +3.3V, it get linked to all kind of unrelated components it shouldn't be.  

@jslain, The problem is that you have placed the little grey cross which is the attachment node of the SWCLK netlabel exactly on top of the crossing point of the nets going to pins 36 (VDD_2) and 37 (PA14). This shorts the two nets together.  If you open the Schematic **Design Manager: ** [https://docs.easyeda.com/en/Schematic/Design-Manager/index.html](https://docs.easyeda.com/en/Schematic/Design-Manager/index.html)<br> <br> and refresh the **Nets**, you will see a yellow warning triangle with a multiple net name warning with (probably) the nets SWCLK/+3.3V to the right of it. The pins 36 and 37 (and others) will be listed in the lower section of the left hand panel.

Please change the **Category** of this topic to EasyEDA Std - Schematic and prefix the title as [SOLVED] because this is not a bug and it is not for the attention of LCSC. Thanks.

Oh thanks! I guess that happened after I moved some wires. You have good eyes

Haha! Not so much good eyes but after years of using EasyEDA and other EDA tools, I  have some good detective skills!
