One of my books appears 5 times on ORCID. Why I cannot merge the 5 on ORCID? Solutions?

I can merge 5 items on Google Scholar and on ORCID. I cannot merge multiple items on ORCID.

I can delete 4 items out of 5, to remain with 1 item, but then I loose the reads of the 4 and the associated score of interest.

I have 5 items for the same book, because multiple authors of this collective books shared it and ORCID asked me to confirm my authorship. Which I did. But now I would like to merge them on ORCID.

Solutions ?
