About the atomic spectral data import using python

I am using astroquery NIST data and trying to import the spectral lines data of H I from specific wavelength range. But when I run the code it is providing me all the possible spectral lines. Earlier it used to run correct. I don’t know what is the issue. I have attached the snip in which the range is set from my wavelength data from 396 um to 460 um. But it is showing all possible wavelengths lines!
