Custom characteristics are not appearing when I attempt iterate through the attributes

Question

the code below successfully complies and returns 3 services with 1 characteristic each, I have copied the uuid for the primary services and characteristic and that doesn't seem to have caused an issue in the nrf connect app 
 struct bt_gatt_attr attrs1[10]; // Adjust size as needed
struct bt_gatt_attr attrs2[10]; // Adjust size as needed
struct bt_gatt_attr attrs3[10]; // Adjust size as needed
struct bt_gatt_service services[4]; // Assuming 3 services

for (int i = 0; i < 3; i++) {
 int attr_count = 0; // Reset attr_count for each service
 struct bt_gatt_attr *attrs;

 // Assign the correct attrs array for each service
 if (i == 0) {
 attrs = attrs1;
 } else if (i == 1) {
 attrs = attrs2;
 } else {
 attrs = attrs3;
 }

 attrs[attr_count++] = (struct bt_gatt_attr) {
 .uuid = BT_UUID_GATT_PRIMARY,
 .perm = BT_GATT_PERM_READ,
 .read = bt_gatt_attr_read_service,
 .user_data = uuids_struct[i].val,
 };

 attrs[(attr_count)++] = (struct bt_gatt_attr) {
 .uuid = BT_UUID_GATT_CHRC,
 .perm = BT_GATT_PERM_READ,
 .read = bt_gatt_attr_read_chrc,
 .user_data = &(struct bt_gatt_chrc) {
 .properties = BT_GATT_CHRC_READ | BT_GATT_CHRC_WRITE,
 .uuid = uuids_struct[i].val,
 },
 };

 attrs[(attr_count)++] = (struct bt_gatt_attr) {
 .uuid = uuids_struct[i].val,
 .perm = BT_GATT_PERM_READ | BT_GATT_PERM_WRITE,
 .read = NULL,
 .write = NULL,
 .user_data = NULL,
 };

 printk("updated
");

 services[i] = (struct bt_gatt_service) {
 .attrs = attrs,
 .attr_count = attr_count
 };

 int result = bt_gatt_service_register(&services[i]);
 if (result) {
 LOG_ERR("Failed to register service %d (err %d)", i, result);
 } else {
 LOG_INF("Service %d registered successfully", i);
 }
} 
 the code below successfully complies but only displays the services, I'm unsure what the issue maybe 
 struct bt_gatt_attr attrs1[10]; // Adjust size as needed
struct bt_gatt_attr attrs2[10]; // Adjust size as needed
struct bt_gatt_attr attrs3[10]; // Adjust size as needed
struct bt_gatt_service services[4]; // Assuming 3 services

for (int i = 0; i < 3; i++) {
 int attr_count = 0; // Reset attr_count for each service
 struct bt_gatt_attr *attrs;

 // Assign the correct attrs array for each service
 if (i == 0) {
 attrs = attrs1;
 } else if (i == 1) {
 attrs = attrs2;
 } else {
 attrs = attrs3;
 }

 attrs[attr_count++] = (struct bt_gatt_attr) {
 .uuid = BT_UUID_GATT_PRIMARY,
 .perm = BT_GATT_PERM_READ,
 .read = bt_gatt_attr_read_service,
 .user_data = &uuids_struct[i].val,
 };
	for (int j = 0; j < 1; j++){
 printk("entering second loop
");
 attrs[(attr_count)++] = (struct bt_gatt_attr) {
 .uuid = BT_UUID_GATT_CHRC,
 .perm = BT_GATT_PERM_READ,
 .read = bt_gatt_attr_read_chrc,

 };

 .user_data = NULL,
 };
	}
 services[i] = (struct bt_gatt_service) {
 .attrs = attrs,
 .attr_count = attr_count
 };

 int result = bt_gatt_service_register(&services[i]);
 if (result) {
