240h retention policy but no data is dropped

SO I have modified the autogen retention policy to 240h and a 1h shard-group-duration.

show retention policies
name    duration shardGroupDuration replicaN default
----    -------- ------------------ -------- -------
autogen 240h0m0s 1h0m0s             1        true

However if I query for data beyond 10 days, I still do get data …

> select CPU from stats_CPU order by time asc limit 1
name: stats_CPU
time                 CPU

> select CPU from stats_CPU order by time desc limit 1
name: stats_CPU
time                 CPU

Why is this happening? What am I missing? Am I not understanding how this works?

I’m using influx 1.3.5.

Thanks!
