Forum privacy settings won't stick

I like to have my email address visible to registered users.

With the old forum, that worked.

With the new software, I go to my Profile, click on Edit forums profile & privacy, choose Privacy Settings, and set profile field Email as visible to Registered Users.

Click Save. Logout. Log back in, check the field, and it has reverted to Yourself.

What gives? Why can't I make my email address visible?

I'm not worried about spam, I get so much that there's no danger of it becoming measurably greater.

Does this work for anyone else?

Thanks!
