Overlap/Outline Clearance Errors

Hello, I'm designing a PCB board and I'm continuously getting similar errors for specific components. As shown in the document below, I get an overlap error for a IC chip (DRV8825 driver) in its base, even when there's isn't anything connected. I get the same plus additional "Board Outline Clearance errors" for a USB shield that am using for a USB-UART converter. Is this an issue with the model itself, or an actual error that I will have to resolve. Let me know if you need more information and thank you for the help.

It looks like the component has two overlapping pads.  Replace those pads in the component with a single elongated pad.

With the SMD pad component, there are two options:

 

1) Use a polygon on the PCB layer and give it a signal name = GND to match the component PAD signal GND
2) Use a rectangle in the component not polygon which will not need a signal name.  You might need to add a another rectangle on top for TStop layer if you want to remove solder mask and TCream if you want to place solder paste. (TStop should be slightly larger).
