Hello,
Czech city "Kladruby nad Labem" doesn't have its full name in Wikimedia Maps, see https://maps.wikimedia.org/#11/50.0560/15.4447 and screenshot below.
The circled "Kl" is for that city. This is zoom-11 specific issue, it's displayed correctly in zoom 12. Maybe maps should be regenerated?
Thanks,
Martin

Specifically, the problem is with those two tiles: 1111/694, 1112/694.
OSM does on-demand tile rendering and makes it easy to request rerendering of dirty tiles; do we have something like that? Or, where can I learn something about our map rendering architecture? The newest documentation I could find is mw:Wikimedia Maps with updates to December 2018 and some links to various more-or-less outdated pages which link to other more-or-less outdated pages.
The technical wiki page can be found here https://wikitech.wikimedia.org/wiki/Maps
Also, about the rendering infrastructure, you should consider that we use Kartotherian, with mapnik + tm source and styles using CartoCSS and OSM database.
