Timing Models doc page not rendering some of the component docstrings fully

For this page. See for example:

PLChromNoise - Model of a radio frequency-dependent noise with a power-law spectrum and
PLDMNoise - Model of DM variations as radio frequency-dependent noise with a

It looks like perhaps it is printing the first line of the docstring only, see for example for BinaryBTPiecewise as well.
