First week of 2019 missing from Weekly Patterns - Foot Traffic dataset?

I downloaded the files for 2019 using the API call indicated in the documentation, but the first file has as DATE_RANGE_START the value 2019-01-07. I can’t find the first week’s data anywhere. Is it possible that it has not been properly uploaded?

This is likely because they wanted to have a complete week of data. The start date for each week of data is Monday and the first “full” week of data started on the 7th.

Ah that makes sense. Thanks for the clarification!
