When entering a contact, options in the “Display as” field make sense as “Surname, Name” but they look funny and WRONG as “Name, Surname” There should be absolutely no comma there, it and it makes no sense to place one. It should not be a difficult issue to solve.
the ‘Display as’ field is open to any name/nickname you want to display the contact under.
If you are talking about the ‘File as’ option, that one can be changed in Tools > Settings > Contacts > General and just choose a different option.
There are all options, with commas and without, to suit anyone’s preference, including a ‘Name Surname’ option.
