Problems running in Kubernetes

[KuLi]

I added the exporter to our Kubernetes Cluster at the nginx Controller.
At the metrics page i get the following errors

4 error(s) occurred:
* collected metric nginx_upstream_response label:<name:"backend" value:"xxx.xxx.xxx.xxx:80" > label:<name:"upstream" value:"xxx" > gauge:<value:0 >  was collected before with the same name and label values
* collected metric nginx_upstream_response label:<name:"backend" value:"xxx.xxx.xxx.xxx:80" > label:<name:"upstream" value:"xxx" > gauge:<value:0 >  was collected before with the same name and label values
* collected metric nginx_upstream_response label:<name:"backend" value:"xxx.xxx.xxx.xxx:80" > label:<name:"upstream" value:"xxx" > gauge:<value:0 >  was collected before with the same name and label values
* collected metric nginx_upstream_response label:<name:"backend" value:"xxx.xxx.xxx.xxx:80" > label:<name:"upstream" value:"xxx" > gauge:<value:0 >  was collected before with the same name and label values

I have 4 endpoints behind this nginx.
I use the latest docker image. Do you have any suggestion for me to fix that errors?

What is the output of the Nginx VTS stats page?
