Orchestrator Screenshot issue

I am facing an error with screenshot. I developed a project in which the portal have the charts inside the dashboard. I have to log in to the portal and take the screenshot and should send an Email. But the description under the screenshot charts are available While running manually but from the Orchestrator run we cannot see the description of the charts!
Even the portal page after we run from Orchestrator includes description in the chart,but while sending mail the description is not displaying and I am unable to understand how it’s possible.
Please provide your urgent feedback for the same or forward my email to the concerns to support me in this regard please.
