Port Forwarding Issues

Merlins Firmware: 378.54_2

I have set the following port forwarding rules via the GUI.

TCP/UDP 5060 -> 192.168.0.10
UDP 6000:10000 -> 192.168.0.10

TCP/UDP 5068 -> 192.168.0.140
UDP 6900:10000 -> 192.168.0.140

I know the UDP ranges overlap, but that doesn't seem to cause any issue any issues... but since upgrading to this version of firmware I'm finding packets that should be routing to 5060 on 192.168.0.10 are being sent to 192.168.0.140

I've no idea why... has any one else had this...
