One object (sports field) is included, but not visible over here. Why doesn't it show up? Can anyone fix this (or tell me how I can fix it)? I've read a lot of inner and outer rings, relations etc. but I couldn't figure out why these below still don't show up completely.

? "ᓇᒣ ?"?
Why "name ?"?
Nicht wahr?
为什么"的名字吗"？名字是？
Pourquoi?
