Integrated Terminal and Debugger produce different results

Question

Objective: Print the name/s with the highest votes

So I was debugging my PSET3 Plurality for probably 8+ hours now. I thought everything was fixed since the result in the debugger was what I intended, but, in my integrated terminal, it produced the result differently.

Debugger result:

plurality/ $ debug50 plurality ./plurality me duck you

.

Number of voters: 7
Vote: me
Vote: me
Vote: me
Vote: d
Invalid vote.
Vote: duck
Vote: duck
Vote: you
me

Integrated Terminal result:

plurality/ $ ./plurality me duck you
Number of voters: 7
Vote: me
Vote: me
Vote: me
Vote: d
Invalid vote.
Vote: duck
Vote: duck
Vote: you
duck
plurality/ $ 

"me" should win right, but why did "duck" did?

My Code(I thought of making a minimal reproducible example, but I don't know how to, that's the most minimal I could think of, I'm sorry. Just scroll all the way down.):

#include <cs50.h>
#include <stdio.h>
#include <string.h>

// Max number of candidates
#define MAX 9

// Candidates have name and vote count
typedef struct
{
    string name;
    int votes;
}
candidate;

// Array of candidates
candidate candidates[MAX];

// Number of candidates
int candidate_count;

//Swapping Function
void swap (char ** xptr, char ** yptr);

// Function prototypes
bool vote(string name);
void print_winner(void);


int main(int argc, string argv[])
{
    // Check for invalid usage
    if (argc < 2)
    {
        printf("Usage: plurality [candidate ...]\n");
        return 1;
    }

    // Populate array of candidates
    candidate_count = argc - 1;
    if (candidate_count > MAX)
    {
        printf("Maximum number of candidates is %i\n", MAX);
        return 2;
    }
    for (int i = 0; i < candidate_count; i++)
    {
        candidates[i].name = argv[i + 1];
        candidates[i].votes = 0;
    }



    int voter_count = get_int("Number of voters: ");

    // Loop over all voters
    for (int i = 0; i < voter_count; i++)
    {
        string name = get_string("Vote: ");

        // Check for invalid vote
        if (!vote(name))
        {
            printf("Invalid vote.\n");
        }
    }

    // Display winner of election
    print_winner();
}

// Update vote totals given a new vote
bool vote(string name)
{
    // TODO
    for (int i = 0; i < candidate_count; i++)
    {
        if (strcmp(candidates[i].name, name) == 0)
        {
            candidates[i].votes += 1;
            return true;
        }
    }
    return false;
}

It isn't necessary to attempt to sort... Just find the highest value and print as many candidates as have attained that amount.

int maxVotes = -1;
for (int z = 0; z < candidate_count; z++)
    if( candidates[z].votes > maxVotes )
        maxVotes = candidates[z].votes;

for (int z = 0; z < candidate_count; z++)
    if( candidates[z].votes == maxVotes )
        printf( "%s - %d votes\n", candidates[z].name, candidates[z].votes );
