Cannot download dashboard template with stepBefore or stepAfter types

Hi,
I tried to download a template file from dashboards view (dashboards-list) but it seem that stepBefore and stepAfter types are not supported. Is there any workaround for that?
{"code":"unprocessable entity","message":"kind=Dashboard field=root[0].spec.charts[1].geom reason=\"type provided is not supported: \\\"stepAfter\\\"\"\n\tkind=Dashboard field=root[0].spec.charts[2].geom reason=\"type provided is not supported: \\\"stepBefore\\\"\"\n\tkind=Dashboard field=root[0].spec.charts[3].geom reason=\"type provided is not supported: \\\"stepBefore\\\"\"\n\tkind=Dashboard field=root[0].spec.charts[4].geom reason=\"type provided is not supported: \\\"stepBefore\\\"\""}

Thanks,
Olli
