The objects use the scripts in the assets but they don't appear there when I click on them.

I have created several scripts for my game and I added them to some of the objects in my assets. As of yesterday, everything was fine. Today when I opened unity, the game works fine, and the objects use the scripts, but when I click on the object, it doesn't show the script that it is using. In the image below, the object uses the movement.cs script, but it doesn't appear.

Does anyone have any idea why this might happen? Thank you in advance :)
