The part about 'imbue weapon' covering up any 'enchant weapon' spells done to a fresh ranger weapon, as well as 'enchant weapon' covering up any 'imbue weapon' stats? If 'by design' is it because they are mutually exclusive? If it's a bug, then can it be fixed?

I really want to roll a wood-elf ranger to hero with a 20/20 hit/dam weapon!
