How do I make my collider be there?

[Salamander42]

There is an error message saying that there is no collider on 2 of my objects but in the inspector there is collider components.

This is the error that I am getting.

and this is the inspector that I have.
Thank you for helping.

try collider2d instead

Collider does not work for a 2D collider. Change it to Colllider2D
