Excessive SageMaker charges for one hour tutorial

Yesterday, I followed the AIM307 (https://gitlab.com/juliensimon/aim307/-/blob/master/aim307.ipynb?ref_type=heads) tutorial on SageMaker using autoML/AutoPilot. It look maybe an hour to do and in the end I deleted everything I could find in SageMaker (endpoints, endpoint configs, models, notebooks, compilation jobs, inference recommender jobs). I checked my usage says I have 16+ hours of notebook charges for Studio-Notebook ml.t3.medium and Data Wrangler Interactive ml.m5.4xlarge. Eye balling what I saw it did, this isn't possible, it didn't make more than 10 ish model and they all finished well under 30 minutes.

What is going on? This is the same tutorial offered at reInvent so it's bonkers to think that it would result in $33 of usage cost.
