I am trying to:
display a map with all the existing items

Link to a page where the issue can be seen:
lien caché

I expected to see:
all of the marker listed (for debug reason) over the map (see the image)

Instead, I got:
just 1 marker shown

As you can see in the image, some of the coordinates are non shown in the debug text AND the corresponding marker is not shown on map. Here is the View code:

[wpv-layout-start]
[wpv-items-found]
<!-- wpv-loop-start -->
<wpv-loop>
<p>MarkerID: mm-[wpv-post-id] - Title: [wpv-post-title] - [types field='posizione' format='FIELD_LATITUDE, FIELD_LONGITUDE'][/types]</p>
[wpv-map-marker map_id="mappaimpianti" marker_id="mm-[wpv-post-id]" marker_title="[wpv-post-title]" marker_field="wpcf-posizione"]
<h6 style="margin-bottom:4px;">[wpv-post-link]</h6>
[/wpv-map-marker]
</wpv-loop>
<!-- wpv-loop-end -->
[/wpv-items-found]
[wpv-no-items-found]
[wpml-string context="wpv-views"]hops! Non risultano partner!!![/wpml-string]
[/wpv-no-items-found]
