This was discovered from discussion #1458. See that post for more details.

I will add an example on seneca to demonstrate the current and expected behavior.

Describe the Problem

Empty string is substituted for {CURRENT_[FCST/OBS]_[NAME/LEVEL]} in MODE_OUTPUT_PREFIX when set within another config section for an instance.

[config]
PROCESS_LIST = MODE(section_name)
...
[section_name]
MODE_OUTPUT_PREFIX = something_{CURRENT_OBS_NAME}

This does not occur when the output prefix is set in the [config] section:

[config]
PROCESS_LIST = MODE
...

MODE_OUTPUT_PREFIX = something_{CURRENT_OBS_NAME}

This is likely occurring in the logic to copy config variables from instance sections into config to use for that instance of the wrapper.
