Just to add, this only happens on my user account, all other user

US even though my regional settings are set to UK.

When you write "regional settings", are you referring to the settings in Excel,
or to the settings in the Windows Control Panel Regional settings.

The behaviour you describe is what would happen if the Windows Control Panel
Regional settings got set to US settings (or the short-date format, anyway).
