Deadline 10.1.18.4 Redshift Export Command Line Args not working

I’m using Deadline 10.1.18.4 and Houdini 18.5.69 / RS 3.0.52 and the Command Line Args in the integrated Houdini submitter do not work at all when using the Redshift Export.

I can see in the log when the .rs file gets loaded in the command no extra arguments are appearing.

INFO: Argument:
INFO: Full Command:

These two lines show no additional arguments from the submitter such as “crop 10 10 20 20”
