Content Organizer - Creates duplicates in the destination library

Question

We have created 2 libraries, one of which have a Content Organizer set on, to send it to the 2nd Library. In the Content Organizer Settings, we decided for duplicates to append unique characters at the end of duplicates filenames.

But I saw recently that we have duplicates of those files in the destination library, without any clear reason. Looks like the file is moved for the first time, but the properties of the item are not entirely filled out. Fifteen minutes later, the duplicate is created, with the random characters at the end of the file name.

Any idea why duplicates are created?

Edit: Just saw that 2 documents were transfered in the 2nd Library with missing properties, but the documents were not removed from the 1st Library, like if they were half processed. (Create the item in the destination Library, but stop before setting the properties & deleting it from the source Library) The user which created those documents did not see anything wrong while doing them.

Thanks.

I have seen file uploads happen almost immediately and then the metadata fields get added as a modification. This has tripped up workflow that used a metadata field. We had to adjust the workflow to pause until modified not equal to created.

Either reduce the metadata required or try to adjust when the workflow or timer job runs to less frequent.
