Sell at actual price 0 displays as 0¢%3 and isn't 0¢

I tried the work around, it did work, they sold the cargo to the city with no exchange of money.

I think this is only a recent bug as I only recently started this save , my previous save had a few ships dropping of cargo repeatedly with no issues, using the sell Cargo order , set price at 0.
