How can I remove unwanted coastline tags?

This changeset added coastline tags to a pond in the Denver, CO, USA area, which is at about 5000 MSL.

I discovered this by running some software that generates scenery for flight simulators. The errant coastlines cause problems.

You can also see the unwanted coastlines by running:

wget -O out.txt 'https://overpass.kumi.systems/api/interpreter?data=(way["natural"="coastline"](39, -105, 40, -104););(._;>>;);out meta;'

I could not figure out how to remove the tags myself in the OSM online editor. I can’t see the tags no matter how I select and try to edit the pond data. Can I get some help with this? I’m admittedly new at this and will RTFM in the meantime.

You wont be able to remove them because they already have been, 5 months ago

Why this acts up for you I don’t know.

NB There’s a loose team of mappers who monitor the ‘new keys’ reports which is updated daily so anything that is judged belony is corrected or binned. Occasionally I get contacted when dreaming up something new (ATYL) proposing an alternate tag not previously known to me.

I have just removed the outer coast line on that pond and removed the coast area on the inner water area and adjusted the natural=water to match the Mapbox Imagery.

Someone may have removed it 5 months ago, but up until a few seconds ago it was there.

Odd, there was a second object as v1, shown by the Better-osm-org plugin as “The object is now deleted”, by you.

Thank you both so much! I pulled the data again with the wget command I posted and it now has the expected (empty) content.
