Can't get rid of white line in Rise lesson header

The bar is inconsistent with progress. I tried everything to hide the bar, changing colors in the theme of the lesson headers because if my theme was dark, the lines were bright white (a partial line). So I changed to light theme and now my lines are my navy brand color. More importantly, as I progress through my lessons, this line moves forward and backwards, even though I have restricted navigation in the divider continue block and was moving forward continuously. If that's a progress bar, it's not working properly. And seems redundant since the menu sidebar shows the progress.
