I remember having an issue with SOAPUI_HOME environment variable on windows platform for the mentioned scripts, so time ago. But absolutely had no issue on linux platform.
This is little annoying. But since you already know the workaround just use the changed files and share to your team. This changes are required when you are doing certain things based on those environment variable.
Usually, there is no defect tracking system and here is the only place for reporting issues. Hope SmartBear team have an eve on the forum and address them.
Thanks for reporting.
