Spontaneous capitalization in richtext

I'm seeing words in a different text color getting an initial cap when in ToolBook they are all lowercase. Below is an example involving the second appearance of the word "scrumptious" near the end of the text. I can provide the .tbk if you wish.
Thanks, Andy
