No surface irrigation, VOLR, VOLRMCH in 0.5 degree regional simulation

[amans]

What version of the code are you using?
ctsm5.2.023

Have you made any changes to files in the source tree?
None

Describe every step you took leading up to the problem:
Typical steps for regional case:
./create_newcase --case /glade/work/amans/cases/I2000Clm50BgcCrop_MRB_0.5_ctsm5.2.023_exp_baseflow --res nldas2_rnldas2_mnldas2 --compset I2000Clm50BgcCrop --run-unsupported
Add regional subsetted surface to fsurdat in user_nl_clm. Other relevant additions include limit_irrigation_if_rof_enabled and use_groundwater_irrigation among others.
Added custom datm streams to user_nl_datm_streams.
Xmlchanged LND_DOMAIN_MESH, ATM_DOMAIN_MESH, LND and ATM NX NY.

For global case:
./create_newcase --case /glade/work/amans/cases/I2000Clm50BgcCrop_ctsm5.2.023_global_test_sfc_irrig --res f09_g16 --compset I2000Clm50BgcCrop --run-unsupported

Setup, build, submit, and runs successfully for all global and regional cases.

Describe your problem or question:
Using a ctsm5.2.023 checkout, my regional simulation over the Midwest United States show empty QIRRIG_FROM_SURFACE, VOLR, and VOLRMCH outputs. The same cases using a previous ctsm5.2.mksurfdat checkout (alpha-ctsm5.2.mksrf.23_ctsm5.1.dev171) had those outputs. I investigated for a global case using ctsm5.2.023, which also showed correct outputs over the Midwest US.

Regional case ctsm5.2.mksurfdat:

What could be causing this issue?

Between the two versions that you mentioned
alpha-ctsm5.2.mksrf.23_ctsm5.1.dev171 and ctsm5.2.023
I am pretty confident that fsurdat files changed. So I suggest that you generate the regional fsurdat file again using the newer version of the code if you haven't done so already.
