Okay, that makes more sense. Your Coinigy was only monitoring the original address, and wasn't aware of where the leftover change was going. But your Exodus wallet had access to both the original address and the change address, so it knew.

I guess that's one of the disadvantages of a watch wallet---you need to make sure it watches ALL your addresses, including the ones you've never used before.

Sorry I didn't pick up on that in your first comment.
