How to modify position of circular targets.

New user here.

What is the procedure on modifying circular points. When an instruction in a path that has two circular points like this (ArcC pWeldB3_40,pWeldB3_50,v500,sm1,wd1,z10,tWeldGun\WObj:=Wobj_tool2; needs to be modified how do you modify the first position. In this example pWeldB3_40. When Modify Position is selected the 2nd position in instruction is modified where I want the 1st position.

If I try and do a modify position using the virtual pendant I get 10421 Planned path not aborted error.
