There is no difference DLE and DA use 5mm bolts and industry std hole centres. SECRAFT also make one that comes with 5.1mm drill

Did you use a pillar drill, or a hand held, and did you put a bolt in the first hole drilled, to stop the jig moving, check the pitch circle diam with the prop washer, ,

Well maybe it was a 'poor'quality DLE jig as I have both genuine DA and DLE (from MacGregor) jigs and If I hold them together they are identical. I've sold lots of DLE type to DA customers with no comment.
Pillar drill is only OK if the bed is flat and 90 degrees to the drill. Props need to be supported on the hub to sit square, so props the TE of the blade is below the hub...
