Can't see fill gradient

Hello,

I've only been working with DraftSight for a few days and doing well so far. Until I applied a fill gradient to a circle. It seems to have successfully applied, but I cannot see the fill in the model view. It does show up in the sheet view. My DraftSight configuration is still on the defaults running on a Windows PC. I have also ensured that "DisplayFills" is set to "On" and "EnblFills" is set to "1".

Thanks.
