Zbrush clipping/slicing problem

WarframeZeeker

Hi, so I am doing zbrush right now and I am having problem on getting rid of the flat surface mesh every time I try to slice something up to remove it in my mesh. Every time I slice or clip something it create a flat surface of it, and I don't get why it does that. The videos that I have watch doesn't do that but mine does. Any clues?

Use the trim brush not the clipping brush

Edit: TrimCurve, TrimLasso, TrimRect or TrimCircle, specifically
