Date acquired faulty in IOS app

Whenever I try and enter date acquired on their app it defaults to the day before. When I try and correct it, it then drops to the day before that, counting back one day each time correction is attempted.

This is a known bug that's still being worked on:

It is sodding annoying and needs to be fixed.
