Vase Mode excesive Z increase

[Edurojolavanda]

Good morning,
I've trying to fix an issue I've been experiencing with a print. I've drawn a model which will be a lamps, printed with a 0.8mm nozzle and 1.5mm layer height. If no vase mode, the model is OK, but the seam looks ugly, so I decided to go with vase mode. I've split it into two proccesses to solve the hole I need at the base, BUT whatever I try, the printer keeps increasing the z axis way more than needed, and for the 2nd or 3rd "layer" it begins printing in the air. I've tried tweaking some options, but no different so far. My printer is a Creality CR10. I attach the different stl versions I tried plus the factory file.

Any help is welcome.
