Docker Monitor of 1 of the node does not show data

Hi all,

A Docker Monitor (1 out of 3) nodes does not show data, both other do.
They are all similar and for sure using the same Docker API version.
It shows configuration data so it must be connecting and communicating.

I do not mind to loose the data from past, so tried to delete the monitor and start with a fresh one.
This does not solved it, but it also shows the data from the past. So its seems the new Monitor is not new but associated with the old data. 

So how can i completely delete the old monitor, including all data, to be sure no metadata, configuration, etc is re-used.

Regards,
Corné
