You’re getting three columns but each framedtext has the width of the 
textblock and two
of your three frames are shown outside of the visible space, using 
framed instead of
framedtext helps.

\defineframed
   [algorithmframe]
   [width=fit,
    align=normal,
    strut=no,
    offset=1ex,
    foregroundstyle={\switchtobodyfont[8pt]},
    background=color,
    location=middle,
    backgroundcolor=lightgray,
    framecolor=darkred,
    corner=round]

\definelines
   [algorithm]
   [space=on,
    before={\startframed[algorithmframe]},
    after=\stopframed]
