I see now. I did see that note elsewhere, but misunderstood it to mean that I would have to use the coded version (i.e. Space:St._Stephen_Church%2C_Toledo%2C_Ohio). While this mistake can easily be contributed to me not fully comprehending the statement, I would recommend to WikiTree admins that highlighting, or at least stating more clearly, that the spaces and special characters are not only permissible in these fields but required. It is pretty counter from what is typical on a lot of platforms (where the use of spaces and special characters are discouraged).
That being said, I can't quite think of a better way to state it. If I think of one I might come back and add it, as just a suggestion.
Anyhow, now I'm just rambling. Thanks for your help Rubén! It's much appreciated.
