Info Canvas Scale Animation

Hi,

I want to create a canvas with general info of my vr game and I added a scale animation so the canvas will show up as a pop-up window and have a close button on top right for closing. When I press the button to show, the scale -up animation is triggered from 0-1 and the canvas is "growing" untils end. The problem is that the close button is not working.

When the canvas is already at scale-up without previous animation, the close button is working and the cancas is scaled-down properly.

Any ideas?
