Reorder the categories list on blog part of site

Hi there I'm needing custom code to reorder the categories list on my site. The list is in the current order as pictured below. But I would like it to be in the order:
All
Youth
Young Adults
Mixed Adults
Women
Men
North Shore
Hibiscus Coast

Any help would be amazing!

This is my site:
https://walrus-sunfish-e5zz.squarespace.com/
Password: password876

Any help would be so great!

And the list is found under: CONNECT/ then under the FIND AN IGROUP button

Add to igroups Page Settings > Advanced > Header

<style>
  .sqs-block-archive .archive-block-setting-layout-dropdown .archive-group-list {
    display: flex !important;
    flex-direction: column;
}
  /* all */
li.archive-group:nth-child(1) {
    order: 1;
}
/* Youth */
li.archive-group:nth-child(8) {
    order: 2;
}
/* Younth Adults */
li.archive-group:nth-child(7) {
    order: 3;
}
/* Mixed Adults */
li.archive-group:nth-child(4) {
    order: 4;
}
/* Women */
li.archive-group:nth-child(6) {
    order: 5;
}
/* Men */
li.archive-group:nth-child(3) {
    order: 6;
}
/* North Shore */
li.archive-group:nth-child(5) {
    order: 7;
}
/* Hibiscus Coast */
li.archive-group:nth-child(2) {
    order: 8;
}
</style>

Thank you for your help! I have done what you said but it hasn't changed it. Any thoughts as to what I may have done wrong?
