I've run into a frustrating error.  I added a single resistor to my schematic and when I Design->Update PCB the resistor shows up on the PCB but has no ratlines. I've updated to the latest version of chrome, cleared cache, restarted the computer, logged out and logged back in. Here is the project.  [https://easyeda.com/Robert37/guitar-amp-v-2_copy](https://easyeda.com/Robert37/guitar-amp-v-2_copy).  R6 is the new resistor.  Here are images. I'm stuck at this point.  Any help would be greatly appreciated. Robert
