The answer you are looking for is part of your initial setup of the board and stencil. This information is to be found in the PCB setup menu/icon. The reason why the stencil loading pins are impacting the frame is because the default setting of the s

|I'm getting in a little late on this but my 2 cents is: We have been using no-clean flux for a few years now but up till last month were still cleaning (the white residue) our boards (all thru hole). Finally did some investigation and found the flux
