Printing Airplane problem 3dlabprint

I bought material and I want to start to make my first plane.

I have Ender-3 V3 KE 3D Printer I try to print part CUB wing L3.3mf from Piper-J-3-Cub
Piper J-3 Cub – 3DLabPrintModel link

Im using .3mf When I put the part in Cura or in Creality slicer is missing the ribs on the bottom pictures bellow

Cura

Creality slicer

In prusa slicer this ribs are showed but the g-code from prusa in not working on this printer even I setup the same printer there.

Can you please help me how to print this ribs ? Why I cant see this ribs in Cura and Creality slicer.
Can you please also give me Ender-3 V3 KE setings for Prusa slicer

Shows the layer for me in Prusa and Creality, though on Prusa the rib starts on layer 2 but on 1 for Creality.

Sorry I don’t understand what do you mean? Can you please explain. I need help thanks

Well you are going to need infill to support the ribs. 10% gyroid should be enough, but it will add to the weight. Have you the lightweight PLA? like this

Yes I have but that give additional weight of the part. Where I can find Prusa settings for Ender V3 Ke?

hi , so was just reading some stuff u have put up on here . and the only way i know to get it to print inside parts is to turn on the odd/even button in Creality for 3dlabPLANES . C how u go with that and make sure that the Detect thin walls is not on so it close the outside walls . dan
