missing weight on flat rate

[Harvest]

While trying to ship a flat rate (env and box) to Australia, it tells me i'm endicia server returned missing weight. I remember i had this problem in the beta, but haven't encountered it since 5.7 was released.

I found that if the weight isn't in the export docs i get the error. If I fill out the export doc stuff w/ weight everything works fine.
