Craig-Bampton Dynamic Reduction OP4 Output Issues

I'm trying to run a dynamic reduction within FEMAP, but am having issues getting it to produce the expected output files. My goal is to get mass, stiffness, and damping matrices as well as data recovery matrices (ATM and LTM) all in OP4 format. When I run the analysis within FEMAP it completes without error but I'm not seeing any of the expected output files generated. I have specified a specific run directory, and the typical analysis run files are showing up (i.e. log file, f04, f06, etc..) but nothing else. I have not tried to run this type of analysis directly in FEMAP before, so I am not sure if there is some added step I need to do or if it is not possible to run this using the FEMAP interface?

I have copied only the relevant input commands from my analysis deck here for reference (copied directly from FEMAP input preview):

ASSIGN,OUTPUT4='HCB_200HZ_STIFFER.OP4',UNIT=30,FORM=FORMATTED
SOL SEMODES
DIAG 8

CEND
EXTSEOUT(EXTID=10,STIFFNESS,MASS,K4DAMP,MATOP4=30,ASMBULK)

METHOD = 1
SET 102 = 1,3,4
ACCE = 102
SET 103 = 932,937 THRU 940,1541
FORCE = 103
