Checking if actor on screen returns true even if actor is not?

I created a new project based on 3rd person blueprint and a test actor. The test actor has this line of code,:

It will print “ON SCREEN” if the actor is on screen.
The test actor has the default billboard dino head image. It is placed towards the right side behind the player character so it doesn’t appear on viewport initially.

Somehow the “ON SCREEN” message will be printed even when the test actor is not within the viewport. I tested it in standalone game.

Solved. Thanks to a friend of mine.

Omg you saved me thank you so much! I wish you good health and the best of luck
