I suspect the part supplier may not know how to fix this (the problem is that the gerber processing code doesn’t handle holes in anything but a circle path.) Below are corrected versions of both parts with the path replaced by a circle and a square which will produce a hole. They are welcome to use the parts on their site so we get working parts out there.
