Flex 6400M Strange Antenna Port Observation

I am using a Flex 6400M w/tuner. I have antennas on both ports. I have SWR/PWR meters on both ports. AutoTuner tunes antennas fine. I am testing with 2 WSJTx sessions. The SCU is connected to ANT 1 for both RCV Slices. Slice A is Xmt ANT 2, Slice B is XMT ANT 1. When I transmit on Slice B-ANT 1, there is no RF output on ANT 2. When I test on Slice B ANT 2, I see about 40 watts RF on ANT 1 and around 95 on ANT 2. I am running the latest SDR software. Is this normal???

    Can you try transmitting on ANT 2 into a dummy load to see if you see any RF on Ant 1? My thought is that you might be getting RF coupling between the antennas.

    If you try the dummy load and still get RF at the Ant 1 port, then it is time to submit a help desk ticket.
