Anonymous , this is correct.

Check there is not timestamp on the date of your table(not date table), and change the data type to datetime, and it should show only 00:00 hour or 12:00 AM

if there is any other time then create a date column

Date = datevalues(Table[DAte column])

make sure Join is single directional

check others
