[Elecraft] K2: KPA/100 Manual Question

[Jferg977 at aol.com]

The manual refers to C12- C22 etc as ,01uF (103) 5% 50V mono  capacitors.  
The ones supplied in the kit are labeled (DELTA  sign) 103k and X7R50.  Doesn't 
the "K" suggest that these are actually 10%  capacitors.
 
in this context, what does MONO mean?
 
Or am I missing something here?
