When ramping lift disabled

Ramping lift is enabled in your project file (via filament overrides). I don´t see any issue.

I reuploaded the project with overrides disabled, and lift height 1mm.

The same single movement from 8mm to 9mm:

Hello @vovodroid, even thought there was initially some confusion with filament overrides, I was able to reproduce your issue. It is indeed a bug. And we are already working on resolving the issue. Thank you for using alpha version of Slic3r and helping us catch bugs such as this one in the early stages of public testing.
