Yes ,it is clearly located out of place, and I have been there recently. It is misplaced in the forest and not on the correct location which is visible in the aerial photo. The playground is is located on a family’s yard. Exploring someones yard is not even acceptable in Sweden where tresspassing rules are perhaps less lenient than other places.
The only thing which really matters is this a playground located on private residential property and is therefore not eligible.
Linking the guidance here which explains it quite clearly (emphasis is mine):
Playgrounds meet the criteria for exercise, exploration, and socialization, and as long as they are not located on single-family private residential property or K-12 schools can be considered eligible.
It strains credulity that this could possibly not be considered to be private residential property of a single-family house.
