Animation bug after opening another scene

I just opened another scene, and when I come back to the first, I got my animation fully bugged.
I animated an object to move, and now my coordonates are extremely different and without a sense (under the map, etc.). Coordonates looks red, also the Animation option. I worked 1 hour to create it and I can’t just re-animate… it took me a lot of time.

Did you fix it?
Did you have to re-animate?
