Stripping run on all grain yielding super low ABV

[BeardedWhiskey]

I made a 40 gallon mash of corn, rye, and barley. I put it in the fermenter at a rather high gravity of 1.12 and it fermented out at 1.01. I'm running my first stripping run and It's coming out of the still at only 10%. Any ideas on why this could be? If it matters I'm doing 5 gallon stripping runs and this is the first one.
