That would explain change over time, but it has problem with why the problem disappears in between 2016 and 2018 and returns in 2020, so even if it is accurate, it seems to be incomplete.

I think the explanation is basically they corrected for the first problem that happened in 2016 in 2018, but the second problem didn't appear until 2020.
