I am utilizing the Keysight 4395A / 4396B combination analyzer in spectrum analyzer mode with the noise format. The units are set to V (volts) and the marker indication is 'nV / Hz'. Are the indicated units in error for this mode?

The limitations are documented within the related manuals as follows:
Refer to the Keysight 4395A Network/Spectrum/Impedance Analyzer Operation Manual , 'Measuring the Noise Level', page 8-36 and the following excerpt:
Refer to the Keysight 4396B Network/Spectrum/Impedance Analyzer Task Reference, 'Measuring the Noise Level', page 3-3 and the following excerpt:
