Support settings for large overhang.

[Graham-becs 0]

Hello Everyone, I am very new to 3D printing and was till today using Creality Slicer software. (It wouldn't print my model despite loads of settings tweaks and diffeent material but it did build good supports - that kept warping) changed to Ultimaker and selected "Generate Support" but nothing appears to be printing (model printing perfect though at moment). I have a 25mm overhang at approx 9.5mm high and are expecting this to warp when it gets to that height. Please see picture and settings. Any ideas what I haven't ticked correctly as I selected defaults?
