missing `Uniqueness Reads` slot from mapping json ?

[PoisonAlien]

Hi Simon, I am trying to parse json files generated by map command but it seems that the Uniqueness Reads information is missing from it. However, they are reported in html file generated from map-report. Is it calculated on the fly while generating html reports ? I have attached a sample files for your reference. files.zip

You can see that Unique Fragments (479609) reported in html is missing in json. Is there any way to get this value ?

Thanks.
