Series in wrong Order

[Nomak]

Hello,
im new to xmbc and to Raspberry Pi. I watched alot of Youtube Videos and read many tutorials.

First i tried most of it on my Win8 PC and it worked everything like learned from the videos.

now i bought a Raspberry Pi 2. Installing Xbian and Configure it was easy and worked pretty well.

I have now only one litte problem. The Episodes under the Seasons arent in the right Order. In my Win8 installation everything worked but on the Raspberry Pi it doesnt.

I tried all options , like "DVD Ordering" but nothing worked.

I have an Folder with the Series name then Season 1, Season 2 and into these folders are the video files named S01E01 for example.

Anyone an Idea what i did wrong?

PS.: Sorry for the bad english...

Thanks

Regards
Nomak
