Rouding value entry increase costs???????

Hi, I use Attain 3.01B. Sometimes attain generate Rounding value entries which dublicate costs. I understand that rounding entries used for some roundings and value is about 0.01, but sometimes we got rouding entries which increase costs twice (for example: costs 548.12 - rounding entries 548.12). We use FIFO. Its seems that we get it when run post costs to g/l batch job. Any ideas, solutions?? Because today there is only one way - delete these entries and correct gl entries. RGDS Gedas
