Turning problem with Missing Link

[n00bCube]

Yeah, when I turn one end of it, it usually kinda turns the other end as well. Is this normal? Is there anyway to fix it?

It's annoying to always have to make sure that one hand is holding the other end tightly so it doesn't turn when you turn the other end.

If I recall correctly, one of the small sides at the end has a screw under the sticker. Loosening that slightly would help.
