iOS Button Shapes Not Working Correctly

Hello Apple Support Community,

I'm experiencing an issue with my iPhone settings. I've turned off 'Button Shapes' in the Accessibility settings, but the background coloring, especially in navigation bars, is still visible. This is happening even though the setting shows as disabled.

I've attached a screenshot for clarity. Can anyone advise on how to completely remove the background coloring when 'Button Shapes' is disabled?
