The preset is 100% wet. But I'm also noticing it across the other effects/presets, not just Reverse (with wet mix rangin from 3% to 100%). It will just randomly be a dry signal, then if I switch presets (say from 2.1 to 2.2 then back to 2.1) it will be ok again. And I have catchup enabled, so I know it's not due to accidentally bumping the mix knob.
I'm running 3.5.0 (4)
