LSF0204PWR - Struggling - Struggling - Really Struggling

Hi All, I'm working with the LSF0204PWR level shifter.  I'm using spi from my STM32 uC (3v3) into the LSF part.  From the B-side (5Vdc), I'm connecting to a MAX7221 but for some reason, it's not displaying the characters on my 8-segment displays.  

I'm not certain if my signals are just not clean enough on the output of the LSF.  I'm actually only passing data in one direction:  An to Bn and that's it.

Can someone advice me how to trouble shoot this, it's really frustrating.

Thanks,

Brian
