The NE and SE Late bodyguards use different textures for their attachments in 6.4, so it might (and that's a BIG might) be that another mod might have code that hasn't taken this into account.
If you open your unit_models folder and open the file battle_models.modeldb using notepad++ for example, then search for 17 ne_late_bodyguard, then you should get an entry that looks like this:-
Code:

If the one you're using looks different to the above, then that's probably what's causing the issue, if so then copying and pasting 'should' fix it. If not then let me know and I'll see what else I can think of.
Does this happen for armour upgraded versions of the NE Bodyguard also (i.e. the gothic looking ones?), or is it just the standard ones?
Best,
