[Client]Kalista doesn't appear as Marksman in the store

When selecting Marksman only, Kalista doesn't appear in the champion list.

Steps to reproduce:

1. Open Store
2. Filter by Marksman
3. Look at the champions

Here are additionnal screenshots:

1. All the champions --> Ordered by release date. Somehow, she appears here: http://i.imgur.com/q7FJobE.png
2. Kalista's page -> She's supposed to be filterable as a MArksman: http://i.imgur.com/4NqboCX.png
3. Bottom of the marksman, to show that she's not there either: http://i.imgur.com/NpksA5P.png
4. Here's the issue'S image again, for reference : http://i.imgur.com/5jo2XkE.png

In every page, I've always had the following settings:

• Type : On Sale unchecked
• Type : Owned unchecked
• Sort By : Release date

I have no clue if this an isolated or global issue. I noticed this while going to buy her.
