1) Indeed, there is a rounding issue. Fixed in the next build of EasyBCD.
2) Your MBR and partition bootsector are in conflict. The MBR says that the partition is FAT16, the bootsector says that it is NTFS. Windows has more info available than bootgrabber does, and looks at the bootsector to make the final decision. It seems the tool you used to either originally create the partition or to convert it from FAT to NTFS did not do so correctly.
