SPI Decode error/ out of sync?

I'm trying to decode SPI, but can't get it to read in sync with the clock bits for the byte.
Is there a setting to adjust for this please?

Hello Ben,
I'm sorry I was not aware you had posted until speaking to Alfie today.
Not sure sharing the project will help as I am simply measuring SPI data to and from an external Silicon labs radio chip by ghost on a E-Blocks 2 board.
Measuring with an external logic analyser is fine.
Are the any settings/ pointers you can guide me too look for?
Thanks and best regards,
Nick.

Hi Nick,
Try adjusting the SPI component properties, e.g. things like the clock phase, polarity and sample point will effect how the incoming data is interpreted.
