Hi Prtahmesh,
it's enough to set only one note for the missing park.
The aerial view shows not really a park ( https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dpark ). It looks like a https://wiki.openstreetmap.org/wiki/Tag:landuse%3Drecreation_ground (with a pitch in the center?). Maybe you will try to add it by yourself? What's the problem? If it fails, I will help!
