Layers Missing?

I’m hoping someone can help me. I’ve been talking to support and no one can seem to help me figure out what is wrong. I am printing a 0.75" cylinder mold that seems to be missing layers closest to the top of the print. Otherwise it looks good.

I am using polylite PLA 2.85, on a Mini 2.

Any advice would be appreciated.

I usually look for polygon errors in the model if a layer issue occurs.

Lulzbot has looked at my files and said they look good. I am getting the same with other files as well. No idea what it can be. Super frustrating.
