SG300/SG200 Auto Voice VLAN

I've got the Auto-Voice VLAN groovin' on my new switches, I've got 3 SG300-52 and 2 SG200-26 to fill in some gaps.

The problem I'm encountering is that when I plug a phone into a configured port for the first time, everything works perfectly.  If the port was configured with VLAN115 as Primary and Untagged, it will add my defined Voice VLAN of 20.  No problems.

When you reboot the switch however or if you disable and enable a port, the Voice VLAN 20 gets tagged on correctly but the port will now show 1UP (VLAN 1, Untagged, Primary)

How do I configure the switches to continue to handle the Auto Voice VLAN correctly, but not interfere with the other VLAN assignments on that port?  So in my example, the 20T would come off, but 115UP would stay on instead of turning into 1UP, 20T or simply 1UP.
