Transparent Menu with Sticky/Shrinking header enabled doesn't work

Hi,
The transparent menu is working great on one of my pages, but only if I do not have sticky/shrinking headers enabled.

How do I fix this so that the transparent header also functions as sticky (remaining at the top) and shrinking when you scroll down.

Here are two screenshots, the only change I make is to disable the sticky header.

Without sticky enabled (how I’d like it to look)
