Too many units!

[Biffordicus]

Hi. in the marketplace, selecting the Stone amount that my people are making in order to buy them brings up a requestor with the following:

"Do you really want to buy 5 units stone units at a price of 0 Gold coins? That would be altogether 0 Gold coins."

It Should read:
"Do you really want to buy 5 units of stone at a price of 0 Gold coins per unit? That would be a total of 0 Gold coins."

Thanks.
