Point Markup not being correctly Exported To Map Image (GE3.15 and SL1.10)

Hi to all

there would appear to be an issue when Exporting a map image when the markup has been added using the RunExternalCommand Activity with the command of AddMarkup or AddMarkupGeometry when the supplied geometry is from a featureset that has had it's geometries unioned

ie the map looks like this

/customer/servlet/servlet.FileDownload?file=00P6000000e88WPEAY

and the exported map looks like:

/customer/servlet/servlet.FileDownload?file=00P6000000e88UjEAI

I assumed that it would be more performant to add one (unioned) geometry rather than iterating through the featureset adding one graphic geometry at a time.

Note that the circle and square markups above were hand drawn as compared to being added by a workflow.

In an example using line markup then the result is correct ie

/customer/servlet/servlet.FileDownload?file=00P6000000e88WUEAY

/customer/servlet/servlet.FileDownload?file=00P6000000e88WZEAY

Thanks
