Only effects sending to laptop speakers?

Hello, I recently bought Cubase. I have a H5 Zoom recorder set-up as my microphone with the output running through the H5 into some external speakers.

I am wanting to monitor a vocal track with some reverb on it, but for some reason when monitor is on, the dry signal is coming out of the external speakers and at the same time a wet reverb signal is coming through my laptop speakers.

I cant see why this would be happening, any advice?
