Sorry about that. Did you try the move to drive option? One of the reasons we added the ability to move the finished archive to Drive was to allow users with unreliable internet connections to use the Drive Sync tool to sync the finished download down to their computer. I know it is a little inconvenient but it should make it possible to download a large archive over an unreliable connection.
It does, there was a lot of debate on whether it should or not. If you have strong opinions one way or the other I would love to hear them as we are open to changing that behavior.
If you don't want that behavior, or just want to export part of your drive (or photos) collection you can expand that product in the Takeout UI and just select certain folders.
