Unexpected export file created with thickjail

Running iocell version 2017-01-24

Hi, When executing the command "iocell export b77fe0ce-e88c-11e6-8d04-0025908675f8" on the thickjail the command completes with "INFO: exporting b77fe0ce-e88c-11e6-8d04-0025908675f8 (cn-jail-docs-01): done!" but the exported file doesn't appear to be a valid xz file and there is no sha256 file. The file created is "b77fe0ce-e88c-11e6-8d04-0025908675f8-thickjail-2017-02-11_11.0-RELEASE" and is much larger than expected. ZFS reports the jail as 5.14Gb but the file created is 8.06Gb which is the size of the data when not compressed with zfs lz4. Does iocell use a different import / export format to iocage?
