Having a column DEFAULT NULL means if you don’t set a value for the column, it will be NULL by default.
Having a column NULL(able) means it can be NULL at all, otherwise it will require you to set a value for the column, either by default or in the insert query. Only check that box if the value is supposed to be optional.
