Share 'My screw tips are showing...please help'

so I am somewhat a newbie to the kreg jig, i really like it, however...   once in a while my screw tip comes out....let me explain..   using 3/4 wood securing it to 3/4 wood, using 1/1/4 fine thread (hardwood) I can have 4 jig holes on the same side of the same board, and for whatever reason i occassionally have one screw tip come out....   what is the problem? the jig? the placement of the board…
