hey so i figured it out. its sort of what you said. modeling it i used a mirror modifier with clipping. and this creates an extra face inside the mess where the mess and mirror meet. it was a basic thing i over looked but once both faces were removed cura slices it perfectly thank you

so im trying to print a simple heart. but it dosent slice correctly. it's filling in the middle where i want to to be blank. after messing around with the scaling i found that at 51% it slices correctly but at 52% it dosents. anyone have any idea why this is happening?
