Material fitting is one thing, and it also affects the mesh size.

Please chekc this:

It will fix the material fitting and the mesh generation for the same wavelength range, after the source spectrum changes.

In addition, make sure the simulaiton time is long enough and let the autoshutoff min to terminate the simulation.
