Custom Legendary Armor

[Smackmash]

Greetings

I'm fairly new to the modding scene (a greenhorn if you ever seen one) and created a Custom Legendary armor Set and a custom NPC for it to spawn in its inventory.

i used this video as a refference to create the armor set:

and this video to create the NPC:

However i ran into some Issues:

1. I tried fixing the armour pieces to only spawn in a certain tier and visually they do (i deleted some AA_'s in the custom armor i created so only the heavy variant was left), but the armor values are still randomized between the 3 existing tiers (light/mid/Heavy) is there a way for me to make said legendary armor pieces spawn in the desired Tier 100% of the time with the appropriate armour values, without them being randomized each time I load the game? Is there a way to create a custom armor piece (by using an existing armor template) to just be Heavy without it being randomized?

2. Sometimes The NPC i created does not have them in his Inventory (when i killed him looted the gear and reverted the Save for instance) even though i created the quest for him and used him as a reference for the item to spawn in

3. I want the NPC also to spawn in either with fixed Heavy gear with appropriate armor values or, equipped with the fixed Legendary set which can be looted of of its corpse, is there a way for me to achieve that? I tried creating an outfit with it but i ran into some Issues. Even though its selected he sometimes spawns in with none of the over armour equipped except for the Custom Gas Mask or with pieces missing (he's using PostWarArmyfatigues as underarmor which is always equipped and so is the Custom Assault Gas mask i made) (the NPC is a male Ghoul...dunno if thats relevant)

anyway sorry for rambling on thanks in advance :)
