Editing Customer Information Doesn't Translate to Calendar or Downloaded Booking Activities

I've had a few customers book appointments and have either misspelled their name and/or email address. I have gone into the Customers section of MS Bookings to update their information however this doesn't seem to translate onto the calendar (incorrect name/email still showing) or the booking activities download file (again, incorrect spelling still showing.)

My hope was if I updated the name/email address in the Customers section that this would update in all other places.

Is there something I need to do to force the update through to the calendar/booking activities?
