League of Legends Skin Installer Ultimate (SIU) not showing all champs

[AssassinsMod]

Hi guys,
actually i'm here because i'm having a problem with SIU's Skin Creator.
Many videos and posts explain how to get riot skins from that tab choosing the one you want in the tree under the champion's name.
Actually my Skin Creation tab does not show all the champs and the various entities results separated (like particles from the champ basic skin)

That's how i see the list:



I'd like to know if anybody has my same problem and/or how can be solved.


Thanks a lot in advance!!
