Hello.
support=ground implies that a light is sitting directly on the ground. That would be a logical conflict with lamp_mount=bent_mast or straight_mast..
The value that you want is support=pole.
I went ahead and updated all the street lights I could find in this park. But you are welcome to double-check to confirm if I missed any. 👍
