I believe what you might be seeing are the user settings for how those things should display (like date format).
Also, per the guru Martin Gillet there is another possibility....
"In the infotype 0002 - Personal Data, across the Formatting field, change in the field "Other format", the format you would like (default is 00 : Last name - First name). It has to be pre-defined in the customizing under Personnel Management then Personnel Administration then Name format (table T522N)."
...so you can change it there.....but as he says...beware because it affects several places.
