unity3d - Animation not working in game as it is in the scene view

Question

I'm trying to make an animation where the word contained in the middle of the screen has its letters that get highlighted one by one using an image overlay on which I increase the alpha from 0 to 0.5 over a short period.

My problem is, even though the animation is fine in the scene view and when previewed, the overlay image seems to be duplicated out of nowhere and always in the same place.

Those duplicates do not appear in the scene view but they do appear in the game view and I can see no reason for them to show up.

Here are screenshots from the scene and game view :

EDIT : After more tests it is definitely an animation problem. The animation runs as it should in the scene view but on some letters, in the game view, it is misplaced and scaled differently.

Here are some more screenshots of what is going on :

Answer 1

わかりましたので、これはばかげた間違いでした。これは、アニメートされたオブジェクトの z 値が -1595 に設定されていることが原因でした。0 に設定するとうまくいき、アニメーションは正常に再生されるようになりました。
