SOLUTION:
Lock stitches are an important part of a design that need special consideration, but are easily edited by the embroiderer if a digitizer is unavailable, using a stitch editor. First check to see how many stitches are locking the section. If there are none, add about 3 single stitches
zig-zagged, placing them close (about 1 mm apart), but not on top of each other, keeping in mind what is seen on screen is not what will happen on fabric. If they are too close, they will be pounded into the same natural "hole" of the fabric. If there are too many lock stitches -- more than 5 -- remove them. If 3 - 5 lock stitches are not enough to lock the open section, the locks are probably too close and are falling through the same hole and could result in pulling the knot back to the top where it's clipped by the trimmers. Use as few locks as possible and space them appropriately.
