Particle console can't add device to product

I’m trying out the new Particle console and created a product. I now want to add a device, but every time I try to add my device I just get a red box that tells me the device couldn’t be added. No real reason. Do I have to remove the device from myself to add it to the product? The instructions don’t say anything other than to “import” the device, but the buttons all just say “Add Device”.
