border radius not working

i've tried both border Bottom Left and Right Radius inside the HeaderImageScrollView, but still no result, i tested this on default navigation options on different headers and everything working fine, but this specific header scroll is having issues, i've tried inside a view, outside the headerimagescrollview, inside contentContainerStyle, inside style={} with a custom stylesheet, and nothing, i don't want to drop this awesome header and start all over again on a different component just because the radius is not showing, i've already spent an entire day figuring this out
