You have a lot of Objects of the same Server, Mountpoint and Version in your list.
Normally the restore only starts one Object per Object-Version and not something like this.
Even with Repositioning enabled it should only be one Object for everything.
Maybe try to set RepositionWithinRestoredObject to 0 in global file.
Or have you selected so many single files from a volume and each spawns a own Object per File? In that case Just give it a try selecting and restoring a whole folder en block.
Have you tried to Verify the Media from Slot 11 that appears problematic? Also re-importing the Catalog with Force option could help in case your DCBF is corrupted and prevents you from properly positioning.
How many Copies do exist of the Object in question? Selecting another Version could help completing the restore
