Troops are semi-ignoring Equipment Rosters on battlefield

[mrj760]

My problem is best described by the picture below, so let me explain what you're seeing.

There are 2 Equipment Rosters I made available to the Khuzait Nomad troop:

1) In the first Roster, the troop has an Iron Saber and a headpiece.​

2) In the second Roster, the troop has a wooden hammer, a pitchfork, and no headpiece.​

​

In the right side of the picture you can see these Rosters registered via the in-game encyclopedia.

So when spawning on the field you would expect to see the Khuzait Nomad have one loadout or the other, right?
Well, once spawned in, they indeed do not have one or the other, but often a mix of both.
On the left and highlighted in blue below are some of the Nomads which are not obeying their Rosters.

From left to right we can see:

1) A sword, but no helmet​

2) A wooden hammer, but a headpiece and no pitchfork​

3) A sword and a headpiece, but also a pitchfork​

4) Same as #3​

5) Same as #1​

6) Same as #3​

There are also examples of ones who have just a wooden hammer with no headpiece and no pitchfork -- making them particularly weak.

Is there a known reason for this? It doesn't seem like an issue that could be addressed via what I'm trying to work with (making an XML mod).
If there is some sort of fix available or resource on where to look I would appreciate it. Thank you.
