MA732 Filter window Register not accepting new values

I have motor application which i have developed using the MA732 evaluation board, i get nice stable control via a PID control loop. i have had 16 custom sensor boards made with the MA732 which when swapped in i’m getting very unstable control. i noticed the filter window setting is not the default 119, but 187 (max) but the IC are not letting me change this value via the SPI. i can change BCT, Trim ect just not the FW i’m using the Macom interface. works fine for the eval boards. any Ideas?
