**BUG** Concise problem statement: The `DRV8825 stepper motor driver carrier` package appears to have some spurious tracks drawn under most of the pads on the bottom solder layer (which is actually the bottom solder mask, not the bottom copper layer) and these are what the DRC is seeing as errors. `All layers` visible: ![enter image description here][1] `All layers` invisible shows spurious tracks on bottom solder layer: ![enter image description here][2] The simple solution is to open the package for edting (SHIFT+F to find it then click on `Edit`), turn off the visibility of the `All layers` layer and then hold down the CTRL key and select each horizontal and each vertical line segment. This selects all the segments. Then press the delete key. This deletes all the segments. (Simply doing a right or left hand drag also selects and consequently deletes all the pads even though they are invisible, which is why the segments have to be selected as described above.) * This is an EasyEDA System package so must be updated ASAP.
