Button assign wrong script

I’ve some trouble with button script.
I’ve an AR scene with a human mesh, and 5 buttons with a script that change the animation played by the mesh.
Everything works fine.
Then I want to add another button with my logo, and a script “btnLogo” that redirects to my website.
Problem is that when I play test the project, all five animation button play the btnLogo script, and the logo button doesn’t work…
How is that possible?

Can you share the project link?
