As already said, the number of renewals is a "cosmetic" bug in admin area only, unfortunately not easy to fix with the complexity of filters in CBSubs, but not related to your IPN error. I was under the impression that it was working, maybe I was unlucky in picking one that works.
Can you please PM me the exact variables for today's Morris IPN that didn't work (as you can see them in your 2co account) ? Want to try reproducing the IPN from here.
As your autorenewals don't work I'm re-increasing the prio of this issue.
