Restore Object from full backup does not work

sma

Hi Vertica Community,
I am trying to restore a table, which has few "set default" columns, but it does not let me restore. It returns the below message, so I removed the "set default" by using the below alter table command (followed the hint provided by the return message) then tried again, but it still not working.
ALTER TABLE prd.table ALTER COLUMN column_names DROP { SET DEFAULT };
Can someone please help, I accidentally deleted some data, need to restore it back.
fyi - I am able to restore some other tables, but just not this table which has "set default".

The prd.table has been restored by restoring it together with the table that has the SET DEFAULT relationship with.
In this case:
vbr -t restore -c full_backup.ini --restore-objects='prd.table,prd.dates2'
