Dictionary Issues Causing Wrong Word Count

I have many names in my novel that are hyphenated. Scrivener counts each one as two words. The dictionary will not allow me to type them in and add them so they are counted as one word. The result is that I have no true idea what my word count is unless I manually check how many names I have and do the math myself. Any suggestions?

Might be worth bringing this up in the Beta forum for Windows Scrivener 3. The main thrust seems to be to get Windows Scrivener 3 polished and out, and it would be nice to see this fixed for the latest version.
