Selected checkbox behaviour isn't removing row correctly when updated

[jrsimp]

I feel like I'm close to working this one out as there are other examples in the discussions that are almost similar in what I'm trying to achieve. I have a column of checkboxes, I want to be able to check a box and have that record be cleared from the table which I'm using Svelte's invalidate to achieve after I've passed the id of the record to a function which sends a POST request to a SQL table. However, although the record is disappearing when checked the next record is automatically checked for some reason.

I'm not sure quite where I'm going wrong. Could anyone help to teach me if I'm missing something specific?

Here's my code

Thanks.

import SelectIndicator from '$lib/components/SelectIndicator.svelte'

export let data: PageData

const testTable = writable(data.testTable)
$: $testTable = data.testTable

const testTableLayout = createTable(testTable, {
select: addSelectedRows(),
})

const columns = testTableLayout.createColumns([
testTableLayout.column({
	header: 'id',
	accessor: 'id',
}),
testTableLayout.column({
	header: `'name',`
	accessor: 'name',
}),
testTableLayout.column({
	header: 'checkbox',
	accessor: 'checkbox',
	cell: ({ row }) => {
		const { isSelected } = pluginStates.select.getRowState(row)
		return createRender(SelectIndicator, {
			isSelected,
		}).on('click', () => updateTestTableCheckbox(row.original.id))
	},
}),
])
