Hello.
Could you please elaborate what are you trying to map here?
What is the meaning of "place:area_alternate=park" tag? This is not a normal tag used in OSM.

Based on the available satellite imagery, these appear to be tennis courts. Could you explain why did you not map them as such? Is the satellite imagery not accurate?
