ROS 5.0 Userman Generate Voucher

Hi
Just downloaded this and wanted to create some test users so i logged into userman went to add users.
Two options under generate 1 for csv and other for vouchers.
Both of them seem to have no function ???
Is there something i must do before this option will work ?
Cheers

Spec
ROS 5.0 on x86 platform
Upgraded from 4.17 but i was not using userman on this version.

Anyone ???

Can anyone even confirm if this is a fault ?

Thanks
