HDT Tails Wearable problem: Floating Tail, Not connecting

[LucentShard]

Hello,

I installed this mod: HDT Tails Wearable
http://www.nexusmods.com/skyrim/mods/58165/?tab=1&navtag=http%3A%2F%2Fwww.nexusmods.com%2Fskyrim%2Fajax%2Fmoddescription%2F%3Fid%3D58165%26preview%3D&pUp=1

and I have a problem with the single tails.
The Multi Tails attach to my character properly and move according to my character.
However the single tails, are not connected, float and act weird. When I crouch, the tail doesn't move along with my body and stays the same height as when I was standing.
Floating, not connecting to anything.

I have installed the latest XPMSE.

Can anyone help me with this problem.

This guy has a detached tail fix

However, his is not perfect, and it looks like the tail is jammed up the asshole instead of attached at the top of the butt aka Tailbone.
