GREENBURGH COVID19: County Numbers Get Strange

This is weird.

County Totals from 5/5:
 
                                         TOTAL.      ACTIVE       NEW

Now the County Total from today, 5/6:
                                TOTAL.      ACTIVE.      NEW

I understand the number of active cases going down, and as well as the number of new cases.  But how do the Total "known" cases fall but the "unknown" rise?
