'{key}' is not a configuration key this grid recognises, so it had no effect. Check the spelling against the reference.

What happened

A top-level configuration key is not one the grid reads. It is ignored entirely - nothing is guessed - so whatever it was meant to switch on is off. Reported once per key name.

The fix

Check the spelling against the configuration reference. A key that belongs on a column, or inside source, is a common cause.
