Mini Wuque M wobbly corners

[Abare Killer]

After the first day of having it, I figured it had the wobbly corner problem, is it just me or is that normal for a Mini Wuque or even a Wuque.

same with mu wuque

I have that problem, too. The corners flip every time!
And you can not tension this cube right, because if it is to loose and the turning is nice, some pieces pop out.
Help!
