Hi AR_FKU,
It looks like you've done some good micro-mapping here. However, once again, by deleting Walthamstow Primary Academy and re-drawing from scratch, some information could be lost if not spotted. The previous way [1] had 23 tags but you have only put 2 tags back on your new way [2]. If you really must delete objects and re-draw, please copy ALL existing tags onto the new object. Better would be to "adjust" (to use your word) what's already there as that keeps the history of the object. [3]

Happy mapping,
Jez
