Metafield for Order returns empty

[adirkol]

I'm using Mobile Buy SDK 11.30 iOS, Shopify API Storefront, and holding the metafield(s) in the Cart object.
After a successful checkout, the Order object is created based on the Cart object, but the metafield(s) in the Object is empty, even though the Cart object had metafields.
The funny thing is that Attributes in Cart returns as expected in the Order object after checkout.

Should the metafield on the Cart should be transferred to the Order after checkout?
