Help!

This is weird.
On a forum im editting.
I installed 2 styles.

But showthread.php and forumdisplay.php
and some other files both uses the primary style.
Index shows normal.

I already overwrited the files with the good ones.
But still they are viewed with default style.

It's cleared up a bit.
Let me explain.

There are 3 Styles:

Fitness (Default)
Air
Tren_z

Fitness has got:
replacement set: Firness
Template set: Fitness

Air has got:
replacement set: Air
Template set: Air

Tren_z has got:
replacement set: Tren_z
Template set: Tren_z

But when i choose Air or Tren_z
It looks likes my style returned to Fitness.
What could be the problem

I found the solution.
