Hello , Asparagus Gazebo.
Please keep in mind that when you added layer = -1," you did not do it in the correct spot.
You added "layer=-1" to https://www.openstreetmap.org/way/153366538, for example. It didn't have to do this. To resolve the overlapping, move the building https://www.openstreetmap.org/way/1177398304 away.
In this changeset, I also addressed another issue and i fixed it:

Could you please check it and correct it, and if you need any help let me know?
Regards
