Why does Cura have weird 100% infill zone?

[yonoodle 0]

Dear all ,  i'm using 10% infill and faced some weird 100% infill zone as the picture shown , how to avoid the 100% infill zone ?  (the object size and wall thickness should not be changed)

This is near the top of this section of the part and you have top/bottom thickness set to 3mm. Which is a lot! .9mm should be plenty. or even .6mm. If you want the tops of your part to be hollow then set this value to zero - or just do it for an experiment and see what happens in layer view.
