In Mr. Robot my DK is missing one weapon and none of the enchants are showing. i have attempted several times to reload it to no avail.
Without knowing your character or - even better - an addon export string we can only speculate about any reason for that.
Generally speaking the most likely reason for this would be your weapon not having strength as its primary stat. As those weapons are almost never worth using, AMR just completely ignores them to not inflate the amount of calculations necessary.
