Hi Edward,

Thanks for your reply by pm. The community center is yet not fixed. Overlapping buildings is not allowed. Please consult the wiki or the fellow mappers in the forum how to fix that.

One (uncommon) solution might be to tag the landuse:
https://wiki.openstreetmap.org/wiki/Land_use

https://taginfo.openstreetmap.org/tags/landuse=community_centre

(This is commonly used for schools and universities but yet not community centers)

Or use

Thanks for fixing!

Best regards
