EzGui always modifies the scene file after play in the editor.

I had made a GameObject in the scene and added EzGUI Button component to it.
Then I play stop in the editor.
When I quit my Unity editor, it shows me a dialog box to save the scene file.
I had did not modify anything.
If there is not a EzGUI button object in the scene, the file is not changed.
Why it changes the scene file?

p.s. I am using SVN for management my project files.
I don’t want to see modified scene file after I just only play in the editor. OTL

I think it normal in unity if u open simple scene and open play and close again u see this message. I think its nothing for worry.

@Sh_Black_Hole
Thank you for reply.
When I had tried it without EzGUI the dialog box did not show. OTL

but if u do something that not change your project like fly over your terrain you see the message. i think EzGUI have some internal variable that change in play mode and when it change change message flag of unity active and show message so when u stop all variable reset so its not important i think
