Rubber Stamp Tool Bug in Painter 2021?

The rubber stamp (clone) tool in Painter 2021 doesn't seem to have any way to change it from the hard edge "mode"  to soft edge like it used to. Is this no longer possible or a glitch or did I miss some setting? I always only used it with the soft edge - right now I'm having to switch my file between 2021 and an older version of Painter in order to use the soft edge stamp. Really busts up my workflow.
