Backup exec 2010 R3 SP4 doesnt see all virtual machines on Hyper-V

Hello

As I said in topic. Backupexec doesnt see all virtuall machines in Hyper - V in selection list, so I cant backup them.

I see virtual machine A  But I dont see virtual machine B.

Any ideas what could be wrong ?

Agents and Backupexec are updated to latest version.

And Agents are also installed on both virtual machines. And I can browse them no problem.
