Ouch! Turns out Guide was reading the "absolute magnitude" of artificial
satellites in a really strange way, resulting in some garbage magnitudes.
I've fixed this; if you go to

and download the current version, the magnitudes should be more reasonable.

It's quite true that magnitude data isn't available for a lot of objects.
If you go into Settings... TLE=(whatever you currently have set) and click on
the line for "Click here for name and magnitude data", things should improve,
especially for more recent objects.
