Items Get Locked In Place - Trying to Hide Object Behind Door

So I have a kitchen cabinet that can open and close. I got it to work where you are able to place items in it and close the door and the items are hidden. But about 20% of the time the items get locked in place and you can't move them unless you turn the item on and off in the inspector or you drag another item behind it. So for example...if the apple stops being able to move around, I can drag the banana behind it and then I can move the apple again. It is very odd. Here are the screenshots...

The 3rd screenshot is just a pic of the rigidbody that is on the fruit.

I have this code on the open door

Code (CSharp):

1. //When you click on this object...
2.     void OnMouseDown() {
3.  
4.         //set the orange door to be inactive
5.         CabinetTopOrange.SetActive(false);
6.  
7.  
8.     }

And I have this code on the closed door

Code (CSharp):

1. //When you click on this object...
2.     void OnMouseDown() {
3.  
4.         //Find GameObject and disable it
5.         CabinetTopOrange.SetActive(true);
6.        
7.     }

And have this code on the inside of the cabinet, which I call contents. It is simply a box collider 2d with trigger.

Code (CSharp):

1. //CHARACTER PICKING UP ITEM
2.     void OnTriggerEnter2D(Collider2D other) {
3.        
4.         if (other.gameObject.tag == "Pickable") {
5.             //parent pickable item to the Contents transform
6.             other.transform.parent = this.transform;
7.  
8.         }
9.     }
10.    
11.     //DROPPING ITEM
12.     void OnTriggerExit2D (Collider2D other) {
13.         if(other.gameObject.tag == "Pickable"){
14.            
15.             //make it so that the object is NOT parented to the character any more
16.             other.transform.parent = null;
17.  
18.            
19.         }
20.     }
21.  
22.     void onMouseDown(){
23.  
24.  
25.         Content.SetActive (true);
26.     }

Please help ... it has been driving me mad for 3 days now. Thank you!

Perhaps it's because of parenting. Are the item rigidbodies? Do you mind uploading the scene?

 

Oh Thank you for taking a look!!!! How should I upload it, when I tried to here it says that it is wrong file type to upload. Thank you!!!!

 

Just provide a dropbox link

 

Ooops...didn't see your comment. I just uploaded it to my server.

 

I'll give it a go and let you know what I turn up

 

Thank you soooo much!
