Hi Slasher,
Good question !
I 'suspect' (read don't know for sure) that the reason for only giving you Slat 1 in Config 1 on the approach is that you can extend the slats 15 kts sooner on a 319/320 and 10 kts sooner on the 321 than if the Config 1 selection gave you 1+F.
And of course this drops the Vls and lets you get the speedbrakes out sooner if you need them. :-))
best regards,
