Calendar List View - Future Months Not Showing

Hello! I created a group calendar within Teams where team members can add their time off through a list. Team members have put in time off for the next three months. In the list view, I can see all inputs for all months but in the calendar view, I can only see the current month (June) listings. 

Here is a screenshot of the calendar view. There should be listings for July but they are not showing up on the calendar view. Any help would be greatly appreciated!
