Wrong country in API data

When I look at https://openchargemap.org/site/poi/details/50850, the location and data is correct in the Netherlands.
But both the json as xml export of Belgium (via a key) has the site listed as Country 26 = Belgium. The NL export does not have this 50850 data.
How come there is this (wrong) difference ?

This is a caching issue across our (multiple) API servers. The cache has been rebuilt now.
