Instanced foliage of another level show up in Cine Camera Actor

Created a new level stripped down to just showcase a product.

Creating a Cine Camera Actor to render a movie the Instanced foliage show up even if it’s not in this level, see screenshot where in the viewer is not showing, in the Camera is showing.

A bug or I need to set some visibility option?

Discovered appear to be impossible to hide foliage, even if was created in another level and using another Floor component.
Hiding it in the Viewport (Show>Advanced, uncheck Foliage) did hide it in Game mode but it’s still visible in the Cinematic Camera.
The only way was to enter in Foliage painting Mode and simply delete all the foliage.
