Hi.

It seems CX2 is creating errors in references used several times in the same article. See for example 820 Olive on frWP, where the reference LAOCDB is used twice :

• First one is correct : <ref name="LAOCDB">{{Lien web |...}}</ref>
• Second one is incorrect : <ref name="LAOCDB">{{Lien web |...}}<cite class="citation web cs1" data-ve-ignore="true" id="CITEREFKim2016">Kim, Chad (13 January 2016). [https://www.laocdb.com/la-development-news/breaking-news-825-hill-49-story-tower-from-onni-group-obtains-grading-and-shoring-permits "825 Hill: Planned 49 Story Tower from Onni Group Obtains Grading and Shoring Permits"]. ''www.laocdb.com''. </cite></ref>

In the second one (which should only be <ref name="LAOCDB"/> to reuse the first one), the content seems to be expanded and the result of the expansion is added to the reference. This of course create problems with the articles, and a big error in bold red in the references at the bottom of the page.

This doesn't seem to be a single case, you have several example in the dump analysis for frWP.
