Element download as a png radius problem!

Every plugin download shapes or groups like this. I need to download with radius.
For see the difference you need to hover image below. There is a white parts all over.

It must be a white background on the group in the back of this green shape. Try to insert Background: none

Thank you for response. But no, Element’s background is green actually.

It must be another group in he back of this green one. Pls share the view link to take a look.
