(Please!)Renderdog seems to be drawing my scene twice

In a project built in the Windows version, an item called frame appears as shown in the picture. However, when you run it as an in-editor viewport or a standalone game and check the render dog, the frame item disappears.

Even if you search the materials, you cannot find out about the item frame.
Does this mean that projects built on the Windows version will be rendered twice in total?
If not, can you tell me why an additional item called frame appears?

sorry. Since the image could not be uploaded, I attached a Google link. :
