Hi Ewarriorzio, welcome to OpenStreetMap. Please don't click Resolve on notes until the information in them has been used to improve the map. For this note, someone needs to click Edit (iD), click Area to use the area tool to draw around the grass area (double click on the last point to finish the shape), then search for grass in the panel on the left. Click Save, add a changeset comment to describe the changes made (eg added grass area in Newcastle) and then click Upload. Hope this helps. :-)
