Multiple listing for facets after editing the list

[qqmyers]

What steps does it take to reproduce the issue?
I was testing other things when I went to a collection's Edit/General Info form and added an additional facet, and then added another one. Looking at the list of existing facets in the form, I began to see doubles (and at QDR, even quadruples).

This appears to happen on beta.dataverse.org (JSF UI) but not demo.dataverse.org, so I'm guessing it is a problem introduced post v6.4. (My QDR test machine has code merged from develop just a couple days ago.

At QDR, I verified that duplicates are in the database, e.g. multiple entries in dataversefacet for the same datasetfieldtype_id and dataverse_id:

I'm not sure what is happening with the display order.
