Why is Cortana showing me meetings for the wrong calendar?

[Windows Central Question]

I use Google calendar for all my work and school shifts. I am also subscribed to my sister's Google calendar to see her work and school info. So whenever I bring up Cortana, she always shows my sister's meeting details before showing mine. If I bring up the details in the calendar though, it doesn't list the meeting anywhere and my sister's calendar isn't even in my list of calendar's on the side. In fact tonight, I just deleted my sister's calendar (because she made a new one for the next semester since she doesn't realize she can just keep using the one instead of making a new calendar every semester) and it is still showing meeting details for the deleted calendar.

Does anyone know how to get Cortana to stop showing meeting details for subscribed calendars and just show mine?
