pghoard basebackup_incoming is keeping old dated folder that is occupying database node disk space

# I have the following pghoard configuration , and should be having only 2 pg_basebackups and noticed that the disk is having multiple old dates pg_basebackups.

Could you kindly suggest the correct configuration how to maintain only the required number of pg_basebackups

pghoard_restore list-basebackups --config /var/lib/pghoard/pghoard.json
Available 'default' basebackups:

Basebackup Backup size Orig size Start time
---------------------------------------- ----------- ----------- --------------------
default/basebackup/2024-10-08_07-24_0 357 MB 3889 MB 2024-10-08T07:25:02Z

As per my understanding, pghoard stores the basebackup in a temporary location (/var/lib/pghoard/temp_data/default/**basebackup_incoming**/2024-10-10_07-25_0/base.tar) , and then uploading it to default/basebackup/2024-10-10_07-25_0 , but when it is trying to delete the temporary location, it is using a different location (/var/lib/pghoard/temp_data/default/**basebackup**/2024-10-10_07-25_0)

Below is the pghoard.json configuration :
```
{
"backup_location": "/var/lib/pghoard/temp_data",
"backup_sites": {
"default": {
"active_backup_mode": "pg_receivewal",
"nodes": [
{
"host": "127.0.0.1",
"password": "pghoard",
"port": 5432,
"user": "pghoard"
}
],
"object_storage": {
"directory": "/var/lib/pghoard/backups",
"storage_type": "local"
},
"pg_basebackup_path": "/usr/bin/pg_basebackup",
"pg_bin_directory": "/usr/pgsql-16/bin",
"pg_data_directory": "/var/lib/pgsql/16/data"
}
},
"json_state_file_path": "/var/lib/pghoard/pghoard_state.json"

Could you suggest what's wrong in the configuration?
