It could be a hardware fault, in which case you should contact your dealer or support@eventide.com.
But, before you do this, consider another possibility. The unit can be set up so that the AUX switches and pedals can control multiple things. It is entirely possible to set it up so that this happens, in which case the multiple overlaid messages can be confusing. I would suggest you do a CLEAR SETUP to return the unit to factory defaults (see UM), then go through the AUX Parameter Destinations and turn them all off. Then only enable the ones you want. My guess is that this will fix it.
