Dear @Saimond,
You can use this life to clear the previous data: bbsp clear policy-stats wan id { wanid | all }
Example: Clear packet statistics of WAN2.
WAP> bbsp clear policy-stats wan id 2
success!
Example: Clear the statistics of all statistics configuration entries.
WAP> bbsp clear policy-stats wan id all
success!
Then use the command: display bbsp stats wan id { wanid | all }


Thank you!
