I swear I entered my middle name when I created an account and made the booking but just noticed my middle name is no where to be found. In the app when I try to add my middle name to the `Passport details` section, it seems to save but when I reopen the details page, the middle name is gone.

In addition, when I go to my profile settings there isn't even an option to enter a middle name.

Is it ok for my middle name to be missing?
