Bsurface edit stroke issue

Hi! I’m trying on Add-on " Bsurface". It has “Add Surface” and “Edit Stroke”. Once I choose “Edit Stroke”, I can’t go back to “Add Surface”. Help???

You might want to go Obj mode, select curve converted from GP in previous step, Shift select mesh you edited and tab edit mode before pressing Add Surface.
Alternatively use GP stroke editing on T-pane GreasePencil tab: Enable Editing, select needed tool and press E key to use the tool.
