PPS topology functionality

Attached is a view of my default PPS. I build and download code, copy and save the main_Rate44.cfg file and modify it for appropriate clock rates etc and resave it as a .txt file. I then load it as a script file in my CS and load this directly into my custom prototype board to the PCM3070 registers via I2C. I wrote script files for the four mux's to load with CS and choose the PPS path accordingly on the fly. I also wrote script files for loading coefficients (adaptive filtering) on all Biquads. I used adaptive filtering on all Biquads. Since I have a mono signal, I only load the left side on all Biquad script files. I verified that every mux, switch, biquad filter works correctly on initial start up. If I load a CS script file for any of the five biquads (ie, 74, 75, 76, 77, 78) and then load script file for the DRC_1 (2:1 w/limiter) the signal path fails. I can restore signal path if I switch to the 1:1 linear DRC_2 but it fails again with the 2:1 DRC selection. I need insight on the fix for this problem.  I can send scipt files if needed. Thanks.
