Hi, I received my Little Magic 2x2 cube today, and out of the box, I noticed something was different from my expectations. The two top red pieces wouldn't move apart from each other, so I couldn't turn my cube in that direction. They seem firm in their spot, and I didn't want to disassemble the cube before posting here. Am I just stupid and this is how 2x2 works, or do I need to send it back? Thanks.
