Content is accessed through the PharmVar API. HGVS and 'PharmVar-style' (accessible on the PharmVar website) positions may differ for indels in some instances which is most likely explained by differences in sequence alignments. Also, PharmVar displays single nucleotide insertions as 'ins' while the HGVS display is as duplications or 'dub' if the insertion is the same base as the prior base.
