Global Array doesn't update while inside while loop?

I have an array of structs, inside the while loop I add things to that array, however when I print out the array I get the wrong output? (The last element added is printed out n times, n being the number of things I added)

I have googled this and I think it is because a while loop in Bash creates a subshell, not too sure.

Any help would be much appreciated (please have patience I am only a student!!)

    nodes[count]= newNode;

    printf("one: %s\n",one); 
    printf("two: %s\n",two);
