Full Pool size not used

[Dakota Pilot]

My backups are running auto ncremental with the intention of eventually enabling consolidation (I tried but it is giving me issues so I'm doing it one step at a time).  I'm basing the setup on

My pool is set for a max of 40G with a volume use duration of 7 days (see below).  It is supposed to auto prune and truncate on purge.  My understanding is that the settings I have should let a volume grow to a max of 40 gig, then start a new one and the volume can be used for 7 days and then it recycles (that is set to yes).  What I am seeing is that the volume does not grow to 40 gi.  For example volume 0 grows to 1.9G on say 8/7.  Then on 8/8 the next backup uses the next volume, volume 1. 

Why isn't the volume growing to 40gig before starting the next one?

Thanks.
