Z1 I can't store and recall mode 1-5 - common issue?  

In the instruction manual it says that it is possible to store 5 different custom (total dots, clamp etc) modes (Page 32-36). It is possible for me to store different modes, but they don't show up in the computer system selection menu (where the current resolution is stated - 960x540=Wide thru). So I can't load my custom modes, any ideas?
