I also have the same problem, gf_entry_id="27" or gf_entry_id="last"is completely ignored. The log also shows countDataFor for 3 entries and loads all entries instead, and displays the last one in the list.
Yeah, display by categories doesn’t show the widget in the other language.
@mheinen1critical it looks like you fixed the issue. Can you let us know what the solution was in the end?
THanks!
