ID identifiers in references are not correctly balanced when new values appear
On items where a CID identifier corresponds to multiple ID identifiers, the corresponding ID identifier is written in each reference. But when new values are added in some property (e.g. the title changes and a new record is added in LEGI database), the references of old untouched values are not updated, they should.
See this example Q36537 for eli:title (P32): the ID identifier references are not correctly balanced between the different values of the title.
