[WEBSITE] item list filter broken

both the Mana regen filter and the health regen filter are broken and only show a few items as having mana or health regen, if you filter by health regen and summoners rift only the dorans shield appears 1 go to http://gameinfo.na.leagueoflegends.com/en/game-info/items/ 2 filter by "mana regen", or "health regen" 3 dont see items like spirit visage, or faerie charm in the list

seems to work every time i try it
