Thanks for the Note. :)

I fixed/adjusted the placement in:

- https://www.openstreetmap.org/changeset/152063368

- - -

PS. And did you know that you can move little objects like this right in StreetComplete?

0. In the upper-right corner, you'll see 3 buttons:
- "Upload" button
- "Layers" button
- Three-Line settings Menu

1. Click on the 2nd one!
2. Choose "Things".

(You can now place/see objects like benches / water fountains.)

3. Tap on the misplaced fountain.
4. Press the "three-dot" menu in the lower-left corner.
5. Choose "It's at a slightly different position..."

Now you can move the fountain to a better spot! :)
