In my machine the two black rounded "things" seen at 1:24 with red rings that connects the milk block with the machine, the one in the right is a little bit "wobbly", while the one in the left is tight and doesn't move at all. It's normal that the right one moves? I'm new with the machine, I have cleaned it like 5 or 6 times and I'm not sure if it's an issue or it's how it should be. Thanks!
