Display bug in Document index (new feature in 10.9: sort by Title) / Viewed in french translation

In 10.9 release note:

now pages which have a displayed title which is different from the title stored in the database are now marked with the symbol "1"

But in french "1" is not displayed at the beginning of the sentence below the livetable.

Note: translation is done here https://l10n.xwiki.org/translate/xwiki-platform/xwiki-core-resources/fr/?checksum=a3a0071033d39bf2 but 1 is not in the source string, it may come from code?
