Hi,
there are several problems with your import:
1. `building=Yes` is wrong, please do not use capital letters (e.g. https://www.openstreetmap.org/way/1157999874)
2. many building shapes contain several nodes more than once (e.g. https://www.openstreetmap.org/way/1158000014 fixed already)
3. ways without any tag (e.g. again https://www.openstreetmap.org/way/1158000014)
4. Useless nodes in building shapes without any angle to next nodes.
5. unconnected nodes without tag (e.g. https://www.openstreetmap.org/node/1158392708)
6. Deleting objects and redrawing new ones on the same spot instead of updating or replacing the old one.

Please, review all your changes at least of the last three or four weeks.
Please, stop importing new objects and work on your workflow which probably would profit from a QA tool like JOSM Validator prior to uploading.
