You need to fix the catalog IDs in the RPK, using these: /d/4218-scripts-2-2-1mwm-and-2-3-0le-superids
Or you can try using this: /d/4168-le2bb93-v2-2
But i noticed many engines get scripted in an odd way, using never seen before catalog IDs(stuff that's neither 2.2.1 or 2.3.0) so doing manually is definitely going to give a better result.
You will need this tool to convert the RPK to a readable format: /d/3712-resource-converter-rpk-converter
This is the tutorial on how to use it, in case you have problems: /d/4212-tools-decoding-and-converting-rpk-files
