Geo Maps Tag/Filter Not working (unless I misunderstand?)

We're using PRTG Network Monitor 15.2.17.2804+, with MapQuest & Openstreetmap. I've created a new Map, on which I want to display a Geo Map showing all devices in a group.

I've created a Device Group which is configured already with all the devices/sensors I wish that are tagged.

I've created a new Map, from clean, and thrown a Geo Maps object on to it. When I filter by the tags I want, I'm being shown all devices that have locational information configured. My tags seem to be ignored.

Yet, when I view the Group collection, I see a perfect example of the Geo Map I'm wanting to create. Suggesting my knowledge of the Tag system is not quite right, or I don't have it configured correctly.

My group has the tags 'sccm-distributionpoints' My device(s) have the tags 'distributionpoints' and My sensor(s) have the tags 'pingsensor'

I've tried a few things, but regardless, other devices that have location information entered, are showing. (none of these devices have tags like I've filtered by so I'm confused)

Any ideas?
