show information gallery only when AI Builder has detected the object

[Puco]

Hi,

when I add a gallery to show the properties of the object detected via AI Builder, I want to make this gallery invisible if AI Builder cannot detect the object (e.g., the picture does not match the trained model).

I set the Visible formula of this gallery as : 

If(!IsEmpty(ObjectDetector2.Results), true, false)

 but no matter whether AI builder can detect the object or not, this gallery cannot be visible any more.

Can someone help me to point out the issue?

thank you.
