fscanf() saves all empty strings and 0s into variables

Question

I have a txt file that looks like this: (str)name (str)last_name (int)weight (int)height and I'm supposed to save it in a linked list. Everything seems to work, up until I print the list and it's all empty or 0 values. I did something very similiar that used a scanf() function and worked, this is why I think the problem might be related to fscanf() function instead.

Here's my code:

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#define ERR -1
#define OK 0
#define MAX 50

struct profile {
    char name[MAX];
    char lname[MAX];
    int weight;
    int height;
    struct profile* next;
};

void print_profiles(struct profile** head) {
    struct profile* curr = *head;
    while (curr != NULL) {
        printf("%s %s\t%d %d\n", curr->name, curr->lname, curr->weight, curr->height);
        curr = curr->next;
    }
    putchar('\n');
}

int readSize(FILE *fp) {
    int lines = 0;
    for (char c=getc(fp); c!=EOF; c=getc(fp))
        if (c == '\n') lines++;
    return lines;   
}

int readFile(char *file, struct profile** head) {
    FILE *fp = fopen(file, "r");
    if (fp == NULL) return ERR;
    int lines = readSize(fp);
    struct profile *curr, *prev;
    curr = prev = NULL;
    
    for (int i=0; i<lines; i++) {
        curr = malloc(sizeof(struct profile));
        fscanf(fp, "%s%s%d%d", curr->name, curr->lname, &curr->weight, &curr->height);
        curr->next = NULL;
        if (i == 0) *head = curr;
        else prev->next = curr;
        prev = curr;
    }
    fclose(fp);
    return OK;
}

void freeNode(struct profile** head) {
    struct profile* curr = *head;
    while (curr != NULL) {
        struct profile* next = curr->next;
        free(curr);
        curr = next;
    }
    head = NULL;
}

int main() {
    struct profile* head = NULL;
    readFile("profiles.txt", &head);
    print_profiles(&head);

    freeNode(&head);
    return 0;
}
