Indeed a fake, the real Bitwarden lives on a .com domain. This .pro one is registered in China. You can look them up here: https://lookup.icann.org/lookup.
Thanks, yes I see now how to do check the registration. I thought I'd take this away and report to DDG, but don't see any option on their search page to report the problem. Sketchy..
Have since learned that the reporting address is abuse@duckduckgo.com.
