White events against white background

[Dr_StrangeTrick]

In my app I have a calendar page to show appointments

The calendar is showing the order date and the order time along with the notes, the category is set to the customer name

So far this has worked great but now I have noticed that some entries are white on a white background and this has caused a few double bookings

There is no specific characteristics etc but I want to know if it’s possible to prevent white on white? or prevent the system from picking white?
