The work-around for this issue is to update the above setting to true, so that each tax-type's value is recorded as a separate ot_tax order-total.

The underlying cause of the issue is that the order's shipping-tax's "Tax Group" isn't captured as part of the order's processing so that reconstructing the order's taxes when all the taxes are bundled into a single, overall value is 'difficult'.
