Title Text Fades with Parallax

Sorry if this is a dumb question, but I’m new to Highend. In the demos of parallax on the HB site, I notice that the text within the background color or image remains constant while scrolling down the page, while the image has a parallax effect. For some reason, my page titles (“Page title within background image”) are also fading as the image scrolls. I would like for them to remain fixed, as in the demos, and not disappear.

Can anyone shed some light on what I might have done wrong or how I can fix this?

Best,

Mike
