[Client ]Chroma Packs in Custom Game don't work

[Client] Unable to chose chroma packs in champion selection in custom game

When I opened a custom game, i wasn't able to chose a chroma for the basic skins of and . Normaly you don't see the splash art of the skin (if the skin has a chroma), you see an advanced ingame model, with the chosen color. You can chose from the "normal" version of the skin and the three different chromas by pressing buttons.

In the custom game I neither saw that ingame model, neither saw the buttons, which normaly allow me to chose the chromas

I only tried it in custom games so far, perhapps this happens in normal games too.

Hope there is enough information
