Some items vmbix don't return value after update Zabbix-server

[Zabbix_User>]

## Version:
Zabbix-server 3.4.6
Vmbix 2.6.0.172

## Issue
I update Zabbix-server 3.4.5 to 3.4.6 and many items in "Template VmBix VM Loadable Module" don't return any value and wait in Zabbix-server queue after this update.

Items who don't return value:
- Discovery rule CPU
- Discovery rule vDisk

- Network Rx (bits/s)
- Network Tx (bits/s)

Other items in the template work correctly.

There are no log in /var/log/vmbix.log and /var/log/zabbix/zabbix-server.log
The command: _zabbix_get -s 127.0.0.1 -p 12050 -k "vmbix.version"_ work !
I restart services and hosts but nothing change.

Any ideas for this issue ?
