I am using the AD9739A-FMC-EBZ and the level translator, U1, is not correctly translating my input serial signals.  How do I fix that?

I probe U1-3 and see a good FMC_SCK and at the same time I probe P4-4 and see a SCK riding on top of a 1V signal.  They should look the same except for the levels and they do not.

 

How do I fix this?

 

Thank you.
