Hi Anor,

interesting, I've just posted a possible explanation for this. 
Please check if the boundary below is divided as described here:

Hi Gerd
 I see you have more case doubling the POI in admin_level 10 when have included place in the relationship. This makes 2 POI

> It implements the following:
> When POIGeneratorHook creates a POI for a type=boundary relation
> with boundary=administrative it searches for a role=admin_centre member
> in that relation.
> If one is found, the generated POI will use the coordinates of this member.
> 
> I see no easy way to compare the tags of the existing
> node with those of the generated POI, so
> as a second step, StyledConverter detects when a POI
> with the same type and name (or empty name) is created at the
> same Garmin coordinates (after style processing)
> If that is true, the latter one is ignored and an info message is logged.
> 
> Maybe for certain types this should be changed to check for a radius
> rather than equality, but that would require complex configuration.
