[Client] Selecting a role in Store > Champions pulls up different champions than in Collection

In Store > Champions, filtering by role (Assassin, Fighter, etc) pulls up a list of champions that does not match the list shown in Collection > Champions and filtering by the same role.

For "Assassin": The Store has Pantheon, Twitch, Tristana, Poppy, Teemo, Malzahar, Jax, Irelia, Vayne, Xerath, Kindred which are not shown in Collection > Champions (Assassin).

For "Fighter": The Store has Taric, Ryze, Nunu, Zac, Quinn, Thresh, Elise, Nautilus, Sejuani, Fizz, Swain, Blitzcrank, Malphite, Nidalee, Rammus, Singed which are not shown in Collection > Champions.

For "Support": The Store has Gangplank and Anivia as supports, but not Collection.

For "Tank": Collections shows Ornn as a tank, but the Store does not.

For "Marksmen": Store has Azir, Gnar.

For "Mage": Store has Varus, Yorick, Ezreal.

These were just the ones I noticed myself, there may be more. The issue is likely something small like mismatching lists or a typo. 10/10 Reproducible for me, also got a friend to check and they saw the same thing. Might be a feature, but seems odd to have Ryze as a Fighter.

Open client, go to store. Click on champions tab. Select "Shown Owned" (though this does not affect the issue, it will show all the champions). Then select the role (Assassin, Fighter, etc). Note the champions shown here. Go to Collection. Click on champions tab. Select the "All Roles" drop-down and select the same role as from the store. Compare the champions shown.
