Invalid statistics for melee_haste

Hello,

I have an issue with value provided by statistics profile endpoint.

/profile/wow/character/archimonde/ïfï/statistics?namespace=profile-eu

I get :
"melee_haste": { "rating": 4294967082, "rating_bonus": 0, "value": 0 },

These values seems invalids

Edit : To complete the analysis, it happens when the character have 0 haste and have an item who reduce haste : Slimy Expulsion Boots (item=193451)

Bug is visible on wow armory : i.gyazo. com/8e7461e1cb12c69403cdd78fb50804de.png
