cnvkit result start position is always 0. What might be the reason?

[altayg]

Hi, I run cnvkit using nf-core/SAREK pipeline. The start position of the results is always 0. Is it expected? If not what my bey the reason for that and how mya I fix it? The below is the example head portion of the cnvkit result using sarek over one of my ctDNA samples with file extension Sample1.md.cns. Because the start position of the results is always 0, during the annotation process (using AnnotSV downstream as sarek annotation does not work for cnvkit), I see around 5K genes per cnv call like a chromosome level event and this looks not ok to me. chromosome start end gene log2 depth probes weight ci_lo ci_hi chr1 0 215956422 - 0.213308 0.256061 1 1 0.233308 0.233308 chr2 0 299993529 - 0.338876 0.264308 1 1 0.398876 0.398876 chr3 0 104445559 - -0.181945 0.189516 1 1 -0.191945 -0.181945

Could you please help with this issue?
