Microsoft Bookings - Print Calendar not showing all information

My office uses Bookings as a Desk Booking application, and at the start of each week our EA publishes a calendar of who has booked. This was working until last week, but now any attempt to print in Edge or Chrome shows correctly in Print Options (Week view, Horizontal agenda), but when sent to print (save as PDF) the actual document to print shows just the 2-month calendar at the top and not the detail of who has booked on particular days. 
I have tried clearing the cache on Chrome, but with no success. It only works in Internet Explorer.
