Actually they're s'posed to guide the water down to the drainage holes, whilst closely covering the plugs, I'm not keen on the idea either but I'm pretty sure that's what they were designed to do if I remember correctly.
Need to make sure your drainage holes are clear though to expel the water, and use air if possible to blow any collected crap around the plug area.
