i made a customPostType Veranstaltungen (events) and place an adressfield.
The Maps-Visualisation on Template of detailpage works well, but now it try to make a view for the startpage wich should show all Veranstaltungen in an Map as Markers.
But there was no marker shown.
The Geolocation field was: wpcf-event-adresse

I create a new view, with
Show on Screen: "Display all Results"
Content Selection: Veranstaltungen
Ordering: sort by posttitle,
Limit / Offset: no Limit
Query Filter: no Filter

And with these content in Loopeditor

[wpv-layout-start]
[wpv-items-found][wpv-map-render map_id="map-3" cluster="on" spiderfy="on"][/wpv-map-render]
<!-- wpv-loop-start -->
<wpv-loop>
[wpv-post-body view_template="loop-item-in-mapsansicht-veranstaltungen"]
</wpv-loop>[wpv-map-marker map_id='map-3' marker_id='marker-[wpv-post-id]' marker_field='wpcf-event-adresse'][/wpv-map-marker]
<!-- wpv-loop-end -->
[/wpv-items-found]
[wpv-no-items-found]
[wpml-string context="wpv-views"]Keine Veranstaltungen gefunden[/wpml-string]
[/wpv-no-items-found]
[wpv-layout-end]

So where are the error
