CI De-Duplication in Single Class

I have a load of duplicate CIs in a custom CI Class under Hardware > Computer

 

As far as I understand, I should be able to generate de-duplication tasks by creating an identification rule in CI Class Manager (using a field that is unique to the individual CI but shared with the duplicates of that CI, in Attributes) and then running the Correctness Health scheduled job.

I've checked the skip_duplicates sys_properties and confirmed that they are set to default (true and 5) and I believe that this means, if there are duplicates (which there are), I will get de-dupe tasks and the "duplicate_of" field will be updated on the CI records.

 

That doesn't happen and I don't know why. Can anyone think of anything I can check?
