Spam in the console

When I load a map with this prefab, the console gives the following spam´s

1. BoxColliders does not support negative scale or size.
The effective box size has been forced positive and is likely to give unexpected collision geometry.
If you absolutely need to use negative scaling you can use the convex MeshCollider. Scene hierarchy path ":\Kobani\WF Custom Island\WF Custom Island\WF Custom Island:16167:/assets/bundled/prefabs/modding/cubes/concrete_cube.prefab"

After I removed the round stone bridge, the frame at the bottom of the tunnel, and the bridge on the lake, the spam stopped. Now, of course, the prefab doesn't look so nice. Please correct the error. Thank you very much

i fixed it

Awesome, can you tell me exactly what the problem was and how I might be able to fix it myself? If something like that happens again. I'm still learning.  Thank you Michael

The problem was the negative dimensions of the prefab
