I cannot set amplitude below 1 V on model 4003A, 4010A, 4011A, 4012A, 4017A, or 4040A. Is something wrong?

No, there is nothing wrong with the unit. Lower range of amplitude can only be set when you enabled the "-20dB" button from the front panel. To enable, push the button so that it is in the pushed-in position.
