Preferences-Recent changes tab has two options that have outdated info:
"Group changes by page in recent changes and watchlist (de-activate for the "Show Wikidata" option below to work)"
"Show Wikidata edits by default in recent changes and watchlist (does not work yet with enhanced changes)"
The patch https://gerrit.wikimedia.org/r/#/c/355799/ fixes the issue - it was deployed in wmf.7
