Synapse 3 not live updating rebinds

I recently bought the Razer Naga Pro, so I had to upgrade from synapse 2 to synapse 3, however whenever I remap the side buttons they wont update unless I restart my whole PC. On synapse 2 I could always rebind them on the fly and they would work. I tried changing profiles and closing synapse 3 and restarting however neither of these options fixed the issue. Is this a normal thing or is there a certain way to make it work instantly like on synapse 2.0?
