Skating Rink Glitch?

What's up with the game-spawned rinks (see my screenshot)? I finally happened to notice a skating rink lot that appeared in Wittenberg literally in the back yard, apparently on a community lot (one I cannot edit/fix). My sims enjoyed ice skating and roller-skating on all three (open) rinks (in the middle of summer (!). But the weirdest part is that two of the rinks (two different roller-skating rinks) are overlapped. This doesn't go away either. They are all usable, but the issue persists. Is this normal?
