[Missing too much of the model's inside]

Now it works, thanks!

[Missing too much of the model's inside]

I'm trying to print replacement mesh for Cat S60 ( https://www.thingiverse.com/thing:2913027 ), but when i try to slice it using Cura 3.6 nearly all of the model's inside disappears, and i don't know how to print it. Also, when i try to double the size of the model on the layers look it's ok. Normal look and layer look are in the attachments.

My printer is Creality Ender 3 without mods.

I also attach my Cura profile.
