Dependency issue with items-clothes/more-better-clothes

It's possible this may be a PEBKAC error, but when using owmerge -s better three separate "better clothes" related mods come up; items-clothes/better-clothes, assets-textures/hirez-better-clothes and item-clothes/more-better-clothes. My assumption is that the dependency order might be better-clothes, more-better-clothes, hirez-better-clothes, but the following issue occurs; I don't know if it's a case of an additional mod being missing, or a naming quirk for the expected file.
