I created a Confluence Calendar that will have all the dates for New Hire Training. I made sure anyone can edit or view the calendar and it is set to the New Hire Space. 
I want to be able to add that calendar to my team's space since we organize a lot of new hire training stuff. However, when I navigate to my team's space and go to Calendars > Add > Add an existing calendar ---- I can't find the calendar I am looking for. I can obviously access both spaces and I can see calendars from other spaces that I'm not looking for but I can't figure out what I'm doing wrong.

Is there a permission setting somewhere that I'm missing or something I need to do to fix this?
