Our allocation does not follow precision (rounding) for the target, but the offset is

Our allocation uses the "Percentage" option in the "Allocated Amount Type" of the Definition tab of the allocation.

The results of this allocation are not following the precision of 2 decimals. However the offset of the allocation is giving us a precision of 2 decimals. This is giving us a 66 cent difference in our results. Because this posts back to PPM ledger, it is causing errors in the ledger.

Is this a quirk with using the "Percentage" option? Our percentage that we entered is a very small amount (.002765), is it possible the preicsion restrition is being ignored because of this?
