Linux terminal tool dosent run one of the getopt commands - c

Question

So I have a simple terminal tool here that makes use of getopt but when I run it everything runs smoothly except "cast -s" it returns "cast: invalid option -- 's'" but it fails silently without any error messages. Ive tried it on different hardware, operating systems and more but it dosent seem to work just right

void print_help(void)
{
printf("Help\n");
printf("> cast -d (deletes file)\n");
printf("> cast -r (renames file)\n");
printf("> cast -c (create new file)\n");
printf("> cast -s (scans for file in directory)\n");
printf("________________________________________\n");
printf("Find an error or a bug? please submit it in the issues section on github\n");
}
int main(int argc, char **argv)
{

int opt_delete = 0;
int opt_help = 0;
int opt_rename = 0;
int opt_create = 0;
int opt_scan = 0;
while ((option_val = getopt(argc, argv, "dhrc")) != -1) {
switch (option_val) {
case 'd':
char filename[65]; //Hope your filename isnt bigger than this
printf("Filename or path to file: ");
scanf("%s", filename); // checks to see if your filename isnt bigger than specified
if (remove(filename) != 0)
{
fprintf(stderr, "Errno: %d\n", errno);
perror("Error msg");
} else printf("%s, deleted.\n", filename);
opt_delete = 1;
break;
case 's':
{
DIR *dp;
struct dirent *dirp;
if (argc != 2) {
fprintf(stderr, "usage: s directory_name\n");
return 1;
}
if ((dp = opendir(argv[1])) == NULL) {
perror("cant copen");
return 2;
}
while((dirp = readdir(dp)) != NULL)
printf("%s\n", dirp->d_name);
closedir(dp);
return 0;
}
opt_scan = 1;
break;
case 'r':
char file[65], new[65];
printf("File: ");
scanf("%s", file);
printf("New name: ");
scanf("%s", new);
if (rename(file, new) != 0)
{
fprintf(stderr, "Errno: %d\n", errno);
perror("Error msg");
} else printf("%s --> %s", file, new);
opt_rename = 1;
break;
case 'c':
FILE *f = fopen("Castdocument.txt", "w+");
fprintf(f, "Finished with maybe no errors? Rename this file to whatever you would like and change the filename extension with ""cast -r""");
printf("File created! (Check your home directory for ""Castdocument.txt"" file and modify that to fit your needs)");
fclose(f);
opt_create = 1;
break;
case 'h':
opt_help = 1;
break;
default: /* '?' */
//print_help();
}
}
if (opt_delete) {
printf("\n");
} if (opt_rename) {
printf("\n");
} if (opt_help) {
print_help();
} if (opt_create) {
printf("\n");
}
}
Ive attempted to run this on a different system to no avail
