To reproduce:
# Translate [[ https://en.wikipedia.org/wiki/Oakland,_California | Oakland, California ]] from English to Polish. (Important: When I tested this, I used [[ https://en.wikipedia.org/w/index.php?title=Oakland,_California&oldid=748841525 | this revision ]]. See the explanation below.)
# Try to adapt the first infobox using the template tool (available starting from [[ https://gerrit.wikimedia.org/r/#/c/308559/ | this patch ]]; usable at the time of this writing at [[ http://cx2.wmflabs.org/ | the cx2 testing site ]]).
- Observed: the template card says "Infobox settlement (!-- See the table at Template:Infobox settlement for all fields and descriptions of their usage. --) **Not available in polski**"
- Expected: the template card is supposed to say "Infobox settlement **Miejscowość infobox**"
If you try to do the same with the article [[ https://en.wikipedia.org/wiki/Hoboken,_New_Jersey | Hoboken, New Jersey ]], this will work as expected.
Explanation: The article [[Oakland, California]] has an HTML comment immediately after the name of the template in the transclusion:
```
{{Infobox settlement
<!-- See the table at Template:Infobox settlement for all fields and descriptions of their usage. -->
|name = Oakland, California
```
As opposed to Hoboken, New Jersey:
```
{{Infobox settlement
|name = Hoboken, New Jersey
```
