After updating to 3.1 firmware all of my IR's were gone from my presets. When I reinsert a IR on path 1 it gives the option for path 2a and I select it. Path 2a won't let me route anything from path 1. There is no option for path 1 for an input. I can create a new preset add an amp, and IR and it allows me to send to paths 2a and b. What am I missing on my existing presets?
