Wrike calendar pulling in unwanted subtask end dates

I have calendars set up for our emails that we're sending, but when I set my calendar to pull in the live date for our emails, it's pulling in subtasks tasks dates, too. It looks like we're sending 50 emails a week instead of only 2 or 3. How do I get the calendar to hide the subtasks and only show the End date for the parent task? 

Right now I have the calendar set to "Classic" and I am manually adding the emails to my calendar, which is not ideal. We have so many emails a month across multiple teams, I'm afraid I'm going to miss something.
