Hi,
In ArcGIS Pro 2.0 when creating a Map Series the application seems to filter the available options in the Name drop down list to exclude fields that are a type 'Double' and 'Date' (from my limited testing).
See below screenshot of table, and then the map series options that are presented:


I would love to use the Police_ID field (it is a type double) as my naming convention when bulk exporting my Map Series, but as I cannot set it as the Name, I am unable to do so.
I would love to see the fields that are type "Double" appear in the Name Field options list.
Cheers
