For example, see the list of references in https://de.wikipedia.org/wiki/Wikipedia?veaction=edit. The reference 1 from read view, defined in the infobox, ("Für mehr siehe: Spezial:Statistik") is missing in VE, instead all other references are shifted by one, duplicating the reference mark "" (once inside the infobox, once in the lead, which is "" in read view).
This is especially awkward on pages with references only inside templates, like https://de.wikipedia.org/wiki/Lycorin?veaction=edit. Though there are two references, VE claims that there are none.
[Note: I always thought this bug has been reported before, but I'm completely unable to find that previous report. So this might be a duplicate, but the original is hidden really well.]
