I cannot setup copper pours in my design

I am new to Upverter but am loving it so far. I do have an issue with my copper pours (specifically on internal layers). My board is a four layer board intended to breakout the pins on a Lattice FPGA. I need a GND pour on the second layer but keep getting the “Pour cannot be self intersecting or degenerate” error. I have found a few other people with the issue on this forum but none of the responses has helped me (including the ever popular, don’t explicitly close the shape that is being poured). Any advice or help would be appreciated. The project is https://upverter.com/SimplexTechnologies/451a57d83a816674/SD_Design/
