Hello. Thanks for mapping. 
A remark.
When you map a building, please map a rectangular from the first till the last node. Here you mapped just 2 lines (3 nodes) and connected them to another partial mapping.
This is not correct mapped.
Just remove the other mapped part and map a complete new building.
See this webpage

and this one
https://www.openstreetmap.org/way/1376271105/history

Please do not connect nodes of adjacent buildings to each other. 
Keep the ctr key down while mapping near another mapped building. 
Map them as separate buildings

Best regards
