What happened

Cards carry a value in the grouping property that matches none of the board's columns, so they are dropped from the model and never drawn. This is the board's silent-loss guard: without it a status of 'Done ' with a trailing space, or a new status the board was never told about, simply vanishes from the wall.

The fix

Either add a column for that value, or map the value onto an existing column before the rows reach the board. A card whose grouping value is null is handled separately and is not counted here.

The smallest fix

createKanban(el, { rows, columnProperty: 'status', columns: ['todo', 'doing', 'done'] });
