message keys not in the catalogue and so ignored: {keys}

The grid (core)

Since

1.6.0

What happened

A message override names keys the catalogue does not contain, so those overrides do nothing. A typo in a translation file is otherwise invisible: the interface simply stays in English and nobody can tell the difference between "not translated" and "translated under the wrong key". Up to five keys are listed, with a count of the rest.

The fix

Check the keys against the default catalogue; the key names are stable and are the ones the grid looks up.
