Retention policy not keeping data

So i have set up a new retention policy and a continuous query to downsample my data and store it for a year. i have used the guide located here
everything seems to work correctly, except my yearly retention policy stores data for the same period as the autogen rp.

so far everything seems correct:

> show retention policies
name    duration  shardGroupDuration replicaN default
----    --------  ------------------ -------- -------
autogen 2160h0m0s 2h0m0s             1        true
rp_365d 8760h0m0s 168h0m0s           1        false
forever 0s        168h0m0s           1        false

but this is where the issue start:

shard 67 should have the start time of early july, when the rp_365d retention policy has been set up. but instead it’đ the same as shard 60 - the oldest autogen shard.
