On my PC in IE6 it works too, I tested before posting. That's why I wonder what causes that.

The count is maybe different because "GS Break" and "GS" are two different names.
Same for DS: you could DS 19 in DS, but they are actually separated. It is not possible to count easily non-complete field values.
Citroen is automatically replaced by Citroën, so all have the good name.
