Export to HTML not keeping chapter show/hide setting

In the Features section unchecking the selection to show the “Show the chapter number on app bar” (in other words to hide the chapter number) does not work in Exporting the HTML. The apk build works but no matter what is selected when exported to HTML for a PWA the chapter button is always present.

We were trying to hide this for an audio only story build. The build used different books for each “page” but only one chapter per book. The chapter number is pointless, yet can not be hidden.
