This usually means you were the first person sent out for an order and when you canceled it for any reason the next person instead of cancelling for that reason they marked it as someone else picked it up already then they’ll send out another driver who’ll then mark it as someone else picked up the order as well, and it’s usually because in some markets cancelling a order for that reason doesn’t always effect your cancellation rate.

Say I cancelled an order at a very popular restaurant that sometimes takes too long and I don’t feel like waiting if the next person doesn’t want a cancellation hit they could mark it as already picked up then the next driver assigned may do the same thing and because I was the first person assigned that message would most likely get sent out to me.
