Since

1.68.0

What happened

The target reported back that it could not apply some removals because it holds no rows under those keys. The router is the only component that can see both sides, so it says so: the rows the route meant to remove are still on screen and will stay there. It is always a key mismatch - the route and the viewer are deriving different keys for the same row.

The fix

Make the route's rowKey produce the same value as the grid's rowKey. A numeric id on one side and its string form on the other is the usual cause.

The smallest fix

router.attach(grid, { rowKey: (row) => String(row.id) });   // and the grid the same
