You are seeing shadows and meaning where there is no great drama.
The dataset was partially corrupt, it was provided by a data firm. This happens. This is why we have scrutiny. Cool your boots until the paper is published.
You do understand why papers are sometimes released prior to review?

"One of the significant lessons from the Human Genome Project (HGP) was the recognition that making data broadly available prior to publication can be profoundly valuable to the scientific enterprise and lead to public benefits. This is particularly the case when there is a community of scientists that can productively use the data quickly – beyond what the data producers could accomplish themselves in a similar time period, and sometimes for scientific purposes that were not anticipated at the onset of the project. "
So in this case the scientists and medics found a problem in the data. Its just what should happen.
