Problems with IterativeSolvers.svdl() routine

The svdl() routine of the IterativeSolvers.jl package is giving me completely wrong errors, even for a 4X4 identity matrix. Am I doing something wrong ?

julia> using IterativeSolvers;

julia> using LinearAlgebra;

julia> K= Diagonal(ones(4));

julia> X,L = IterativeSolvers.svdl(K,nsv=3,vecs=:both);

julia> display(X.S);
3-element Array{Float64,1}:
 8.097516300046776
 6.159726694870877
 5.198283129557383

julia> A=X.U * Diagonal(X.S)*X.Vt

As you see, the singular values are all wrong and the factorization does not lead to the original matrix.
