When the market opens here is the data for 3/24/2020 @ 9:31:00 AM:

Symbol: KR, Time: 3/24/2020 9:31:00 AM, Open: 31.44000000000, High: 31.53000000000, Low: 30.98000000000, Close: 30.99000000000

When I look at Yahoo Finance @ their minute chart for that day, it says:

Open: 31.50, High: 31.68, Low: 31.21, Close: 31.22.  

It appears at least for 3/24/2020, all the data appears to be wrong.  I haven't done additional research to see if it's beyond 3/24/2020.
