When making rhenium field point arrows in quantities of 100, with "just" 100 swamp ash lumber on me, and the rest of the materials in the guild depot, I am still getting the invalid component message.
I *suspect* it is because the recipe needs swamp ash lumber in 2 spots, and it is confused by the combination of the two slots, and the need to look multiple places for both - perhaps they're stomping on each other's resource requests?
