What happened

A tile named an aggregation the panel does not implement. Rather than refusing the tile, the panel falls back to count, so the tile still renders - with the number of rows, not the number you asked for. The key carries the unknown name, so one typo produces one line however many tiles share it.

The fix

Use one of the aggregations listed in the message, or pass a function (or aggregation: 'custom' with one) to compute the value yourself.

The smallest fix

tiles: [{ id: 'revenue', label: 'Revenue', aggregation: 'sum', field: 'amount' }]
