Inconsistent home page statistics vs dataviz (different numbers and labels)

1. The statistics displayed on the home page and the data visualization stats are inconsistent. Stats says "Participants", Dataviz says "Users" (it should be "Participants"), there are 534 participants and 678 users!. Votes (should actually say "Supports") are 1002 in Stat and 999 in Dataviz counter. Proposals are 522 in Dataviz counter and 519 in Stats.... There are more. 2. I expect to see the same numbers and the same labels/categories. A full and careful revision is needed. 3. I found this in meta.decidim.org with v.0.15
