Hercules C2 Cargo Grid

Recently picked up a C2 for cargo missions, and im finding that the cargo grid seems to be bugged. The entire front half of the ship seems to not have a functioning cargo grid. Reguardless of box size, nothing clips to the cargo grid.

Based on the specs, the C2 should be able to hold 20x 32 SCU boxes, but can only snap about 12 boxes to the grid at any given time. Is this a known bug? Or am i doing something incorrectly?
