You have "Only retract when crossing perimeters" parameter enabled, therefore retractions/z-lifts are not performed in such cases.

Only retract when crossing perimeters

It is confusing.. Two parameters located in different places are related with each other.. Shouldn't this relation be explicit. I would never thought it is related..

Will there be done any changes to make this behaviour explicit?
