Unable to select correct Index in map visualisation

Objects are one of the supported types for geo_point, there's plenty of posts on this topic here at discuss, I've found this one where a colleague suggests to refresh the index pattern in Kibana.

What do you see on your index pattern?

Another thing to try is to do a simple geospatial query against your index to confirm your data is stored as geometries, for example:

GET bitvise-geo/_search
{
  "query": {
    "bool": {
      "must": [ { "match_all": {} } ],
      "filter": {
        "geo_bounding_box": {
          "geoip.location": {
            "top_left": { "lat": 90, "lon": -120 },
            "bottom_right": { "lat": -90, "lon": 120}
          } } } } } }
