Missing backed up data to restore

[FZANV]

When trying to restore backed up files from tape, not all files “Objects to restore” appears in the Choose Objects window. Only one file appears in the Choose Object window.

If I try to restore this file I get the error:
TapeMedium not found (MediumFamilyId: 0, MediaSequenceNumber: 1)

Veeam indicate that the backup job, that I want to restore, was successfully. Also I inserted the same tape in the drive.

I tried to Inventory Drive and Catalog Tape but does not help.

I am using an old tape drive:
Dell PowerVault 110T DLT VS160

Can someone know what the problem could be?

THANKS
