Unable to import file descriptions

Problem/Motivation

Importing nodes with file fields doesn't import file descriptions

Steps to reproduce

Create new drupal 9 installation
Add and configure Content Sync
Add file field to Basic Page content type and turn on description option
Create a new basic page node
Content sync export
Dump database
Add files with descriptions to node
Content sync export
Restore from dumped database
Content Sync import

Files import, but description fields are blank. Descriptions fields are in the yml file exported by content sync. If there are prexisting files with descriptions, those descriptions get wiped out too.
