when the day of the month is selected, a green circle is automatically placed on the day/date and will keep the same date in the following month. For example, I selected July 20 but did not actually "add" a task or event but the date was circled in green. Then August 20 was circled in green, as was September 20, October 20, November 20, and December 20. How do I get rid of the green circle as it is not a true 'event or task'. There is no delete option.
