Simultaneous-Use works for PPTP/L2TP but not OpenVPN

I have several VPN servers and 2 radius servers. I run OpenVPN, PPTP and L2TP. PPTP/L2TP will respect the simultaneous-use flag but OpenVPN does not respect the simultaneous-use flag on my primary radius server. It seems to work just fine if I use the failover. Here is the debug output. The only things I can see that is different between the primary and backup is OpenVPN has caps in the primary and for some reason [detail] expand: %{Packet-Src-IP-Address} is not displayed in the primary logs. Any advice would be a huge help.
