Hello. Thanks for mapping.
 A few remarks.
Do not cluster buildings and map it as 1 building.
Do not give generic names to buildings.
Just building=yes is sufficient.
Did you not notice the Issue triangle warning for that issue ?

You did not map the visible round buildings as well as the gray/brownish rectangular building
They ought to be mapped as well.

See the image on the comment section.
Best regards and keep mapping
