Property value '1535526000000' isn't valid (details: 1535526000000 is at 7:0:0.0 UTC, not midnig

When trying to import contact lists today, I keep getting the error "Property value '1535526000000' isn't valid (details: 1535526000000 is at 7:0:0.0 UTC, not midnight!)".  I do have a column with dates, but no time stamps.  This error is preventing me from importing any lists.

Simply copying and pasting the entire spreadsheet into a fresh file seems to solve the problem, but even then, I'm sometimes getting a separate error "Can't process date '43341' using MDY format (from column 'last_campaign_date')".  Last campaign date is the date field I referred to, but that is definitely not the contents.  It's a date formatted as a date (8/29/2018).  It returned the exact same error for every row in the spreadsheet.  I import lists like this every day and have never seen errors like this before.

It seems like it was a temporary bug.  I'm not seeing it anymore.
