Junk printed on the last 3-4 layer

Hello I need help. I'm trying to print this Caps and I get junk printed on the last 3-4 layer.

Please see picture before and after.

I have tried 0.9,.14.19 , solid....

I always get the same.

Thank you 

The top lip is too thin. If you use the advance settings outer contours button and raise it to .1 or .2 it should work fine

Minimum sliceable wall thickness is 0.45mm for high poly models and a bit more for low poly models.

Your model is 0.36mm thick at the top.
