Deleted Data gets restored back Automatically after aerospike restart

Operations

I deleted data on aerospike using aql with below command :-

delete from namespace.sets where PK='1';,

But after delete as soon as I restart aerospike.

All data that was deleted recovers back automatically.

Why? and How?
