Google Search Console's Lost Data Directly Related To Indexing Bug

I was confused as to why Google Search Console lost 16-days worth of data if the indexing bug lasted from April 5th to April 11th. Furthermore, if the indexing bug started on April 5th, why did Search Console have data loss from April 9th through April 25th? Shouldn't there be a one-to-one overlap in dates to the data loss?
