Hi-
Okay, the Decay issue you're experiencing – that's expected for the reverb and by design. It's a BH style reverb where Decay is increasingly pulling the whole signal through, and Size and Decay work together to create the total reverb decay time.
The Vertigo Verve modulating up is because the Pitch Shifters are set to 11c and 18c respectively – so each time they are fed back into the reverb, they will climb slightly.
Hope that helps.
