Meshes not rendering correctly in build

I have a scene in which there are about 30 entities that are created using ConvertToEntity (Set to convert and destroy). Earlier, these entities used a material with the Sprite-Lit-Default shader in URP and I used the default checker sprite that comes with Unity for testing. It worked fine at the time.

I added my own sprites three days ago and when the scene is loaded in a build (there is no problem in the editor), the sprites are scaled up and appear at a much lower location than intended. The colliders for the entities (I am using Unity.Physics) are still in the correct locations.

For now I am just going to make the scene all over again and test it in a build.

Maybe it's a problem with how the LocalToWorld component data is set? Although to be honest, I probably made some mistake while making the scene.
