I tested if I can replicate the problem and appears that I have the same issue with Lotus Notes restore in the GUI with DP 7.03.
I can also add that there is a problem in Virtual Environment restore using GUI. For example, if I select to restore Hyper-V vm to directory and select the directory, then change to Optins tab, then change back to Destination tab - previous selection in Destination tab Restore to directory is gone.
Back to your problem,
You can try to use omnir command from CLI.
