Incorrect gem (color) in socket

[vindicias]

Describe the bug
When I 'suggest reforges' on my gear (MM hunter), including gems, i notice an issue with my shoulders. Currently i am using Yaungol Slayer's Spaulders which, in game, have a blue socket. Yet, when i suggest reforges, the sim places a red gem (delicate primordial ruby) in it, which in game is impossible.

To Reproduce
In the Marksmanship hunter sim, equipping Yaungol Slayer's Spaulders for example while having the BiS items in the rest of the slots, then using 'suggest reforges' including gems, will reproduce this problem.

Expected behavior
I expected the sim to put a purple gem in the slot (glinting imperial amethyst), which is (as far as i know) the best gem for a hunter in a blue socket.

You can put red gems in blue sockets in game, the reason the sim does that is because you'd propably be over hit-capped using a glinting imperial amethyst
