This lists my package classes and the class help pages.  Instead, the "Arithmetic Operators" help page is always loaded.  I can load the pages I want via links like \linkS4class{classname} in my package help page.

The problem is the parsing:  that is parsed as `?`(stats4::mle - class), 
i.e. there's a subtraction there, not a name with a hyphen in it.  So 
you're seeing help on subtraction.

You can get what you want with class?stats4::mle.

I'll see if I can fix the advice from ??.
