There's a few things it could be. A VST plugin as Tim mentioned is one possibility.
Is it an analog input that you are processing? Or is the right channel pure digital silence?
Can you PM me a config backup file? You can create a backup file in BreakawayOne on the page
Home > Common > System > System Information
Click on "Backup (Save) Configuration Zip" button, and it will ask you where you want to save the .zip file.
This way I can look into it much closer.
