unrar-free fails for multi-volume files but unrar doesn't

unrar-free fails for multi-volume file but unrar doesn't. Output for both:

I typically use unrar-free and in the past I have similar issues with some other files until I realized they weren't corrupted and unrar handled those multi-volume files fine.

Let me know if I should provide additional info.
