Like the OP said, it's a convection oven. It does not work if the air cannot circulate. The holes exist to facilitate the air circulation.
I use a sharpened credit card, also useful for cutting LA catering tape, to make an X in the foil over the holes then fold the foil back. If my credit card needs sharpening I use my finger and poke the foil. I have also found that second generation Tempe Mission Palms pen will do the trick in a pinch.
