Why is it that after 15 minutes of posting this I find an answer.

The answer was to switch there to lowercase (not sure why)

Rserver to rserver

Rapp to rapp

in scripts, and forms

Yes the system does not like mixed case variables.

What’s more is, if you have module information setup on your system you could use `auto_modules_r` to populate that list for you instead of hard coding it.
