CDCE62005 EVM does not allow writing to SPI register 0

Other Parts Discussed in Thread: CDCE62005, CDCE62005EVM

I am using CDCE62005 Control GUI to test out my settings on an CDCE62005evm board trying to solve a lock issue. Whenever I load my settings I see them applied for a second, then register 0 gets updated with all 0s. The GUI also updates to reflect this, output driver 0 is disabled, divider before smart mux is hiZ and  core frequency is 0. I am attaching my register settings for reference, but I don't think settings would cause this:
