I realized that the text was there just displaying in white. So after re-declaring the styles explicitly in the templates it works and renders the text.
I compared my composition with respect to CSS and JS in the solution to your demo and one that I can create locally using the default Kendo Template recipe in VS2017 where the text renders normally and I see no difference. I reviewed my styles prior to again putting the styles below in every template and did not see anything conflicting.
