Zsuite beta thin walls issue

I wanted to print a plane but some details are removed.

A10 Polymax PC M200 .zprojx (6.5 MB)

The walls are too thin. If you uniformly scale the model to 120%, they remain after slicing.

Thank you for your help. It s strange but with PLA it works. Why zsuite do not propose to expend small tickness like some other slicers ?
