Hello,

This object is a bit weird:
https://www.openstreetmap.org/relation/15978161

You created an invalid multipolygon with two adjacent outer areas, and gave it a dual tagging that says: "This is both a social facility AND a car park."

The problem is that nothing will be rendered or searched properly.

I suggest you examine this again.  Make it two contiguous areas, one for the car park and one for the woonzorgcentrum.

Hope this helps.
