Radial Menu Issues

Can anyone tell me if i’m going wrong somewhere in making my radial menu? the children all spawn in the top left corner of the canvas panel even though i’m setting position of the slot so i’m not sure, and the Set Brush (slightly offscreen) isn’t putting the image in at all or even making it the size set in “Make SlateBrush” (the size worked in an overlay panel but not in the canvas panel, the image hasn’t worked in either panel)
