Chrome Store Themes are Incorrect on Brave Pages

I added a custom Chrome Store “Theme” to Brave. It only partially loads correctly. Basically, everything at the ‘top’ of the page is correct. The field (the main area of the browser) has the base color, blue.

However, the color gradient, gold, is missing. Also missing are images in the bottom left and bottom right corners. They show (left) the author name and theme name, and (right) a comical image of a sick bird.

This is not critical. But it is annoying. I paid for the theme years ago and am disappointed that it is not displayed correctly when everything else in the theme is properly shown.

See attached Snip showing Chrome and Brave using the same theme.
