zfs send/recv cant send properties

Running Ubuntu 19.10 on both the send and recv systems.

I can't send properties. If I don't include the -p switch, all i good.

If I include the -p switch it looks like it is going to work, but it hangs like this:

sudo /usr/sbin/zfs send -vp -I tank/vm@2019-11-02_22-41-35__daily__batch1 tank/vm@2019-11-05_18-26-01__daily__batch1 | /bin/ssh back1 sudo /usr/sbin/zfs recv -vu backup/vm

send from @2019-11-05_18-24-41__daily__batch1 to tank/vm@2019-11-05_18-26-01__daily__batch1 estimated size is 2.50M

20:03:30 2.06M tank/vm@2019-11-05_18-24-41__daily__batch1

Then I have to kill it.

Any thoughts?
thanks,
