Modular control rig break in 5.5

Hi everyone!

I’m encountering an issue in Unreal Engine 5.5 with the new Modular Control Rig. I have a character where all the bones have been renamed based on the default character “Manny.” However, for some reason, when I use the arm module, it shortens the arms of my character, and I can’t figure out why.

This is what the character looks like before using the arm module:

And this is what it looks like after using the arm module:

I wonder what might be causing this issue. Any help would be greatly appreciated!
