If you move a crafting material into your account bank, and then from there move it to another characters inventory, there is no way to move any material or item that isn't explicitly labeled as a component, IE it MUST say "Component" in the item name or there is no option to move it to crafting materials

Second, there is a work around for this. Go to a mail terminal and send all the r&d things that are in your main inventory to yourself. Then you can accept them back and they will go to the proper r&d inventory.
