Under NVBU 10.0.1, when setting an 'Offsite Location' value for tape media from the Web UI, one can only input the offsite location value manually.
The pull-down menu offering already existing offsite locations is no longer provided, as it was the case under 9.2 (Media Properties).
Workaround:
There is no current workaround for this issue.
Status:
This issue will be resolved in a future version of NVBU 10.
In the meantime, you will have to input the offsite location value manually.
