I cant see any useful information on your image, but if you have problem with colliders, check something:
if your game is 2D:
-you need to use 2d physics colliders and rigidbodyes.
-the 2d colliders maybe need to be on same Z axis position
You can got much more help, if you make better description about the current problem and better image about the problem, because I cant see anything useful on this image.. where is the ground? and where is the character?
