Question about protect elf file

I wrote a helloworld program with VMProtect SDK included, and also markers was used. While I loaded it into vmprotect, and tried to protect it, No Functions for Protection was showed in the Project form.
I used the same source code to compile on Both macOS and Windows, all show a correctly recognized functions for protection.
Is this a bug for ELF parsing?
