Some footnotes are erroneously highlighted

Hello,
I’m using Ms-Word. Some footnotes are randomly highlighted blue, see screen. This is not new, happens almost all the time. My only workaround, is that I click on P+Add/Edit Citation, and simply “Update Citation.” Then I goto away from the citation itself, then “Update Citations and Bibliography.”
See Screen.

@Fr_David_Elias could I trouble you to share a document where this happens with us, so we can try to reproduce? Also, please let us know which citation style you are using (or send us the .csl file if it is a custom one). Feel free to share via in-app messenger or email (support@paperpile.com). Thanks in advance.
