Biblatex Bibliography

[Wolfgang Engelmann]

In the LyX Biblatex Generated Bibliography the menu point Rescan
shows
scan for new databases and styles (if the mouse pointer points on it)
but there is no way to select the styles (in my case biblatex-spbasic)
In options?? (I have there maxname=2)

In Documents>Bibliography is, however, a place Biblatex citation style 
where I inserted biblatex-spbasic (and under processor biber)

if so > but there is no way to select the styles (in my case 
biblatex-spbasic)
wouldn't it be better to remove
  and styles
or, better, to tell the user that the style has to be inserted in 
Documents>Bibliography
