I've created a new Publishing Target and associated database, but I've run into an issue that I can't seem to solve. The new target, "review", is present but won't populate on Publish. On performing a full Site Republish, it shows no errors but simply returns:

Job started: Publish to 'review'
Items created: 0
Items deleted: 0
Items updated: 0
Items skipped: 2
Job ended: Publish to 'review' (units processed: 2)

(Doing a Republish on the Home node with sub-items/related included is the same except it reports skipping 57 items)

This is configuration file for adding the DB. The DB itself was created as a copy of Web. Inspecting the review database directly after the publish there are just 11 rows in the dbo.Items table (down from the 1000+ that were present before attempting a publish):
