Doubler not working?

Hi guy and gals, I just updated my cortex, and am using the Gojira plugin, and when I turn the doubler on, nothing is happening? I’ve tried switching outlets (multi is default) thinking it’s a stereo/mono issue but that doesn’t change anything. I’m using a Bose s1 pro as my amp, otherwise it’s normal signal chain. Any insight would be appreciated!

Thanks.
