Horde pvp potions suddenly have alliance rep. requirement

About 2 weeks ago I bought some Major mana and healing draught (potions) and Warsong Gulch Field Ration (food) at the horde vendor at the wsg entrance.
I have already used a couple of them without problem, but suddenly now the items have gotten a reputation requirement with Silverwing Sentinels. They just seem to have changed from horde to alliance items. Which makes no sense as I am horde and can't get silverwing sentinel rep.
I actually can't use the items anymore.
Example:

Hope this can be fixed for me. Thanks in advance.
(Also made an ingame ticket but aren't getting any response on that).
