Restore problem HP DP 9.0.5

I have a problem with resoring Filetype backup from StorOnce softwre deduplication volume mounted on media server.

While restoring with wizzard on source tab , displays warning Internal error: DbaXXXX functions. (can't read contents -> gray out).

Linux Cell_manager ( same system MA i StorOnceSoftware dedup) 9.0.5 version.

Thanks for any help or direction where to look for workaround.
