FX13, stereo or mono patch?

Hi C&G guys and others on this forum.
I’ve been using the organelle since one year now but mostly as a synth with lovely patches such as 1008, analog style and so… But now I was trying to connect my volca fm to the organelle and using the FX-13 patch. It’s works well but in mono, on the screen I can see only the left signal (the jack I’m using is stereo and with other effects patches it’s working in stereo perfectly) I don’t know if there something wrong because the video presentation from C&G is showing the patch working in stereo. Any suggestions or help? Thanks :blush:
