The current armor registry names/ids in-game are shown here:
Helmet uses <armor_id>helmet
Chestplate uses <armor_id>body
Leggings use <armor_id>legs
Boots use <armor_id>boots
The helmet and boots are just like vanilla id's, but the chestplate/leggings uses body/legs, which are not vanilla.
For example, enderite_body and enderite_legs would be the ids for commands in-game for Enderite Chestplate and Enderite Leggings.
Please change it so when it generates the mod, it uses chestplate instead of body and leggings instead of legs. In the visual section, please add a new parameter for each piece of armor in the advanced settings for the registry name after the main mod element registry name.
