Vortex Wireless 2 is sending MIDI out to module but I don't hear anything

Edit Subject

I am trying to use the Vortex editor.
At some point, I am did something where my module receives CC from the Wireless 2 but the module is NOT PLAYING THE SOUND.

What did I do wrong?

I tested the output with MIDI-OX from the Wireless 2 and everything looks fine.
I updated the firmware to 1.1.5 on this Wireless 2.
I also have tried to reset the Wireless 2 to factory preset.

When I have the thing connected by dongle or USB cable to my module, I see MIDI CC going into the module but I hear no sound from the module. The module works. it's not the module.
