If I understand your situation correctly, I think what you need is NOT
smoothing but interpolation.   See the "filler" operators such as


I think you obtained the result you did, because a smoother operator
(of which sbx is one) requires all the n datapoints within the
smoothing window are defined,  where "n" is the number after the colon
in "l=@sbx:n".
