Transmog bug

[melrus]

I transmogged my belt to look like this one: http://www.wowhead.com/item=32339/be...primal-majesty but now there is a white stripe across my robes which isnt part of the belt. https://imgur.com/a/tRwlb A screenshot of what i mean, ive tested it with different belts and the stripe is only there with that belt.
I don't know where to report this bug but can you have a look at it?
Thanks
