Sorry for the long delay, looks like you recover files from an HFS+ disk, and R-Studio cannot save their forks correctly. Most likely, the files themselves are recovered correctly. See more in R-Studio's on-line help: Data Recovery on HFS/HFS+ File System.
So the questions:
1 What is the file system of the disk you're saving files to?
and
2 What is the files system of your computer?
