MemberName in Queue

Hello!

I have updated recently major asterisk version from 1.8 to 11.
In queue_custom_general.conf I set new option log_membername_as_agent = yes.

I use dynamic agents and manage they via dialplan
AddQueuMember((500,${CUT(CHANNEL(name),-,1)},${name},${CUT(CHANNEL(name),-,1)})) here variable ${name} is MemeberName.

After that I saw in queue_log 1397044861|1397044860.22540|500|SIP/2516|ADDMEMBER|

Why Memebername value didn’t write in queue_log correctly?

I have tested it in another server and saw
1397043506|1397043504.4|500|112|ADDMEMBER|

Gyes? Can anyone has the same problem?
