Objects sticking on corners

Hi, I have a bunch of floor cubes (scale: 10x,5y,1z) all lined up next to each other along the x axis. Im having a problem where if I set the friction of both the floor cubes and a smaller (1x,1y,1z) cube to 0 so that the cube just slides along the floor after being given a force, it 'stumbles' or gets caught on the corner when it reaches the next floor cube. This is just for prototyping and proper art assets will be swapped in at a later date, but I'd like to get this cleared up now. If anyone knows why this is and if it can be fixed that would be great thanks.
