PLAYER NOT ACTIVATING TRIGGER WHEN ON TOP OF THE COLLIDER! IS THIS A BUG

Ok, this is hard to explain, when my player goes through a "triggered" block on the wall side, the player goes through freely. but if the player lands ontop of the collider. the player just finds it as a floor and doesnt go through or anything, is this a bug? If someone can help please i cannot keep making my game :) The players components have a collider(Not triggered) and a rigid body love you guys. my player script is here

using UnityEngine; using System.Collections;

public class CharacterPersonController : MonoBehaviour{

 }

     {
         Velocity.y = moveSetting.jumpVel;

     } else if (jumpInput == 0 && Grounded ()) 
     {

     } 
     else
