FATES not recognizing changes to zbedrock

Hi FATES folks. I’m helping my lab group to set up some experiments using FATES where we want to change the depth to bedrock. After playing around, I’ve noticed that when I change zbedrock in the surface data file (generated using the subset_data script from ctsm/tools/site_and_regional) CLM without FATES will recognize the modified depth to bedrock, but FATES does not. FATES doesn’t recognize zbedrock at all. Is this correct? Is there a way to modify depth to bedrock for FATES?

For the image below the FATES and CLM cases were run the same expect for use_fates = true or false.

Let me know if you need more information.
