Hi Grace, I might have made a mistake, I'm sorry! At the moment we are "flooded" with HotOSM building additions in Nicaragua. 
Many of these HotOSM contributors are new to OSM and they don't square out buildings. Many these additions are far too big, some have really odd shapes like triangles. It looks like some users don't care at all.
I try to help this people to improve the quality. It is not always totally clear which user did which building shapes, except by checking each building individually - which I probably didn't do when I contacted you earlier.
So I'm really sorry for that!
Take care, Michael
