When I try to create a field, it seems that I am forced to choose a default value.However, the "sex" field, it is created without default value, I would like to do the same.I would like to do the same, I make a mistake somewhere?
Please could you specify what is the field type you are creating ?
Thank you for the report.
The problem is that "Default Value" field isn't always populated, when creating the field, but this fields isn't mandatory and can be left unspecified.
Also do you have any custom lists ?
