Warning when running Samplot vcf

[MeHelmy]

Used command
samplot vcf -v SV.sort.vcf -O png -b data.bam --important_regions gene_region.bed -d results --sample_ids "data.bam" --gff Homo_sapiens.GRCh38.100.chr.gff3.chr.gz --command_file   samplot_commands.sh

I have results (but the gff annotations are not shown), the region should contain 7 DEL and 5 INS, only 6 deletions exist in the index.html file.

There is this warning:

samplot.py:2951: UserWarning: FixedFormatter should only be used together with FixedLocator
  curr_ax.set_xticklabels(labels, fontsize=xaxis_label_fontsize)
